Episode 412: The force on a conductor in a magnetic field

Having reminded your students that magnetic fields can be found near permanent magnets and in the presence of an electric current, the next step is to show how the ‘field’ can be quantified. Again, students should know that a conductor carrying a current in a magnetic field will experience a force and will probably remember that Fleming's Left Hand Rule can be used to find the direction of that force.


Demonstrations: Leading to F = BIL. (15 minutes)

Discussion: Factors affecting the force. (15 minutes)

Discussion: Formal definitions. (20 minutes)

Student questions: BIL force calculations. (20 minutes)


Leading to F = BIL

Several quick experimental reminders are possible.

Tap 412-1: Forces on currents

TAP 412-2: An electromagnetic force

These lead on to a further experiment in which the relationship F=BIL can be established.

TAP 412-3: Force on a current-carrying wire


Factors affecting the force

The experiments above lead to the conclusion that the force F on the conductor is proportional to the length of wire in the field, L, the current I and the ‘strength’ of the field, represented by the flux density B. (There is also an 'angle factor' to consider, but we will leave this aside for now.)

Combining these we get F = BIL

(It can help students to refer to this force as the ‘BIL force’.)

Students will probably know that electric and gravitational fields are defined as the force on unit charge or mass. So by comparison, B = F/IL, and this gives a way of defining the 'magnetic field strength'. Physicists refer to this as the B-field or magnetic flux density which has units of

N A-1 m-1 or tesla (T).

A field of 1T is a very strong field. The field between the poles of the...

Public School-Uniform: Decision Hanging on by a Thread

...Classical Argument Position ENGL 123 Public School-uniform: Decision hanging by a thread Today’s youth face a different learning environment that was not as prevalent in years past. Peer in on any one of the more than 98,500 schools, and notice the difference. Public schools have morphed into more of a hangout and social hour-type atmosphere, as well as become the new “red carpet” to display the latest fashion trends. That is not all. Reported cases of drug and alcohol use, weapons brought into school, and violence and bullying have drastically increased over the years, and not just in the high schools either, but in all grade levels. As each of these problems take a seat at the head of the class, quality education breaks for recess. Although the factors attributing to the recent increases in these issues are many, one viable solution to mitigate some of the problems is for all public schools to require their students wear uniforms. Many advocates for this initiative, me included, strongly believe that mandating the wear of uniforms will reduce the alarming numbers for violent behavior and bullying, as well as alleviate any socio-economical barriers that currently exist; therefore, they will become the catalyst which brings the focus back to education within the classroom. For those parents who oppose the idea of uniforms, and who believe that mandating their child wear a uniform while attending public schools violates the First Amendment and stifles their......

School Uniforms

...Every school is in essence a learning environment. That which aids learning is acceptable, and that which hinders it should be unacceptable. Add to this the fears of school violence and student safety and you can see why many school boards are calling for school uniforms. In this article we will look at school uniforms and the potential benefits and problems associated with school uniforms along with legal issues and whether they are in fact truly effective. School uniforms serve a number of purposes. A good deal of research has been undertaken in regard to the use of the school uniform, and the net result has been the wider use of school uniforms in more recent years. Also to increase school safety, to encourage our students to experience a greater sense of school identity and belonging, to encourage an improvement in student behavior, to reduce school clothing costs, to encourage a high level of program participation and to improve and expand academic excellence. School uniforms range from the formal to the informal. Some schools that have implemented school uniforms have chosen what one usually thinks of in connection to Catholic schools: nice pants and white shirts for boys, jumpers and white shirts for girls. However, most public schools are turning to something more casual and more acceptable to parents and students: khakis or jeans and knit shirts of varying colors. The latter appear to be more affordable too because they can be used outside of school. Many......

Children focus on television, magazines, and videos that set the standard of what they should look like and dress like, however school uniforms allows every student to focus on school and not worry about what they look like or what their neighbor looks like. Everyone knows a child or is a proud parent or grandparent of a child and every child needs the opportunity to learn in an environment that promotes a stress free atmosphere. Underprivileged children may not have the finances to keep up with the latest fashions, schools that require uniforms help to promote equality among the students. According to, an online site to debate and read the opinions of others believes that uniforms help to create a sense of equality among students. When the most popular girls in school are dressed just like the most unpopular girls in school, this can removes the stress of worrying about how you look and can be a way to create unity among students. In addition, school uniforms prepare the student for real life situations where they may have to wear a uniform or follow some sort of dress code.

School Uniforms

...School Uniforms By Kendall Cole June 2014 AED/200 - CONTEMPORARY ISSUES IN AMERICAN EDUCATION Instructor: Christine Duhamel University of Phoenix Since the late 1990's school uniforms have been worn in mostly urban school districts across America. Initially, they were opposed by stakeholders, especially the students. School uniforms were accused of stripping students of their creative expression. After a while, uniforms were tolerated, it was realized that wearing uniforms helped to create a positive learning environment. “School uniforms are being advocated for a range of social, educational and familial issues” (Bodine, 2003, p. 67). There are so many issues students have to deal with when they attend school. Some of these issues create negativity in the student’s educational career. Stakeholders must come up with ways to help make learning environments and experiences more positive. Wearing school uniforms will help to create a positive learning environment. Since the turn of the new millennium, school uniforms have become common place and a trend in large school districts across America. In 1996, former President Bill Clinton mentioned school uniforms in his State of the Union Address (DeCosta, 2006 p. 49). Former President Clinton said, " And if it means that teenagers will stop killing each other over designer jackets, than our public schools should be able to require their students to wear school uniforms" (Mitchell,1996).

Why the Society Should Be for Wearing Uniforms

...Running Head: FOR SCHOOL UNIFORMS Main Title: Why the Society Should Be For Wearing Uniforms Emillye Edington Southern University of Shreveport Instructor: Joyce Cottonham 1 FOR SCHOOL UNIFORMS 2 Why Society Should Be For School Uniforms There are many resources that suggest that uniforms should be worn nationwide not only in private schools, but public schools as well. If we take into consideration that it may help children to behave more effentily in school then school systems could be better as well. There are many reasons as to why it could make children behave better. Bullying in schools could be decreased, unity could increase, and parents could save money by purchasing uniforms. Although bulling in schools is a worldwide epidemic that can create negative consequences, if the students wore uniforms we could minimize this horrific behavior. Students should not have to worry about if their clothes are good enough to please someone else’s expectations. According to Laura Clark, “Having a uniform helps to reduce bullying in school. Students at schools without uniform codes were liable to be bullied for the way they dressed the study found.” Teenagers who took part in the Oxford Brookes University survey said dress codes acted as a social leveler and reduced the risk of children being picked on for wearing “weird” clothes. Maybe we can decrease bullying by having school uniforms for the dress code. Having every student dress just alike......

...more prone to go for a uniform or their regular “street clothes?” Eighty percent of adolescents are more likely to pick the regular clothes because they want to have their own style (Mitchell; Knechtle 3). Do students’ feel more confident when they are dressed in a uniform? A girl in “Dress Code Blue” said, “I feel uncomfortable in uniforms, and if I feel uncomfortable, then I feel lazy and don’t want to do anything” (DaCosta, 4). It is a drag to go to school knowing that people are more than likely to look like everyone else? A lot of students are between a rock and a hard place when it comes to this decision. Did you know that Americans spend around $1 billion per year on school uniforms? (School Uniforms). The topic on whether or not to wear uniforms is not beneficial to the students, or to parents, due to the fact that they’re unaffordable, they do not prevent gang affiliation, and they do not give students a sense a sense of individuality. One of the major issues students’ have with uniforms is that they are unaffordable and parents should not have to buy the uniforms. Over the years parents should have complained about how the uniforms are so expensive and how they are having financial problems. “In addition to finding that the level of parental perceptions of the cost of uniform, the survey elicited strong comments from parents on the subject of school uniforms” (West; Tidwell; Bomba; Elmore 1).

Sexism in School Dress Code

...discussions. And, while everyone is in theory affected by dress codes, girls and LGTBQ youth are disproportionately affected by them. Challenging schools to align unexamined, traditional dress codes to contemporary values is a tangible place to start if you're interested in teaching kids to live in a diverse, tolerant society. Of course, many parents are not interested. When it comes to girls, skimpy and skin-baring clothes are often the primary issue. Kids know that many words, like "unladylike," are code for "slutty." Other words that are frequently used include "distracting" and "unprofessional." Many teachers worry that girls' skin will "so addle boys' brains that they will be unable to concentrate." Boys, and apparently in Iowa, adult men who can now legally fire "irresistible" women, we are told, simply cannot concentrate in this environment. So, what exactly is wrong with saying girls are "distracting"? I mean, everyone know this, right? •Who gets to be distracted? And, whose distraction is central? What is a girl supposed to think in the morning when she wakes up and tries to decide what to wear to school? They aren't idiots. The logical conclusion of the "distracting" issue is, "Will I turn someone on if I wear this?" Now who is doing the sexualizing? My daughters would never have thought these things without the help of their school. The only people these policies...

...ready for school. As I walked past my mirror, I stopped and took a final look and thought “Boy, I look fabulous today.” I continued on my way down the stairs, and when I reached the kitchen my mother saw me and said “Oh no, you are not going to school looking like that.” Why not" I asked," I look fabulous.” Mom replied “You may look fabulous, but that outfit does not meet dress code. Go change!” I sighed and reluctantly went back upstairs to change. As I was changing I thought to myself if there were school uniforms, life would be easier. There would be fewer arguments with your mother, more money to spend on other things, and people would not be judged or judging others by what they wear. First, uniforms will help decrease arguments in the morning before school because they restrict what you can wear. I know what you are thinking. You are thinking that would totally stink having to wear the same thing every day. This is not all that bad; you get to sleep longer. The biggest decision of what to wear is made for you. Plus a little bit of extra sleep can do wonders. Besides there are other ways of expressing yourself other than the way you dress, like using your words and your actions. Secondly, the cost of school uniforms is a lot cheaper. You would just have to buy five shirts and five pairs of pants to get you through the week. These should last you all school year because you would not wear them anywhere else, besides who wants to be seen in a school uniform at the......

...Effect Essay Do School Uniforms Restrict Students’ Freedom? What do baseball players, flight attendants and even restaurant’ clerks have in common? They all wear uniforms to do their work efficiently. School uniform requirements have been controversial among students, parents, and school officials. Do school uniforms restrict students’ freedom? Some students and parents believe that forcing students to wear uniforms ignores their basic rights. But uniforms have lots of strong point for students because school uniforms can help students when they are more sensitive and emotional than any of time in the whole life. School life is between adulthood and childhood. In other words, students are experiencing sudden change in their life; so they are very sensitive about their appearance. Especially, students tend to follow fashion trends because they accord importance to things that they are able to see. Also, they feel and share anxiety together. They can feel comfortable when they notice that they belong in the same group, which contains similar people to them. This means that students can get confidence and emotional stability when they are same with others in a group. Thus, wearing school uniforms eliminates the problems of worrying about appearance and fashion because all students wear school uniforms. Also they don’t need to agonize what to wear in the morning before going to school. One effect is that students can save the time to prepare for school, instead.......

...and arguments that were worked out by administration and local school, often at the request of parents. There should be a dress code for students for several reasons. Many public schools today are making dangerous decisions and these decisions may end up saving someone's life. The decisions are about school uniforms and dress codes. Public schools are beginning to open their eyes to the real world and see what their students are wearing and what the clothes are about. Some schools have banned any clothes with inappropriate symbols or sayings. Baggy wear is very dangerous. Schools are now even taking away the privilege of those clothes for the reason that weapons and other dangerous, illegal items may be smuggled in under loose pants, hats, shirts and jackets. The cost of maintaining a stylish wardrobe can be expensive. Many families have more important things to spend their money on than the image of school children. The dress code may be a way to keep the costs of school down for those families. In some schools, there has even been fighting or stealing based on expensive sneakers or jewelry. There are many clothes in fashion for boys and girls which are not appropriate for school dress. Good taste and common sense should dictate parental and student choice of school clothes. The school will determine what is not appropriate dress, even if it conforms to current fashion. Also, school dress should not be viewed as a daily fashion show. In......

The Effects of Public School Uniform Policies

...The Effects of Public School Uniform Policies Taresha Y. Hemphill ECPI University Abstract Public school uniform Policies are not a solution to all school problems. Some problems will still exist. However, the improvements that the mandatory uniform policies have made across the nation are indisputable. Public school uniform policies will continue to reduce school violence and gang activity and overall help create a productive and safer learning environment. It will take more work to correct the school systems, but they will only get worse if something is not done about them. Even though school uniforms are a small step to improving the violence in public schools in the United States, it is better to make that small step than do nothing at all. There are vast opinions over what students should wear to school. Some see a student’s style of dress as an expression of who they are and dress code policies as a First Amendment Rights issue. Others see a student’s style of dress as a safety issue. School Dress Codes and Uniform policies have been challenged in PTA meetings, the classroom and in the court room. The main reason for having these policies is to create a safer, more productive learning environment for our children; not to strip away their freedom. We should allow students to express themselves and their individuality. However, this does not mean that their expression should be......

This essay will also explore some of the different controversial issues between schools and female students due to the dress code policy, and the different ways females use to fight back.

I think there is so much debate over it because it does have an effect on how a person feels at school and maybe by limiting self-expression it could change how a person develops in their life. If it is a mandatory rule and a student is uncomfortable or feels strongly against it could actually cause more problems and may have a lasting impact on how a person responds to authority in the future. A lot of people feel that dressing the same could and does help eliminate bulling and bring their focus more on academics Due to ongoing shootings and in school violence Author Maria Wilde (2015), states that public schools should have the option of requiring uniforms to help identify intruders in the school and prevent gangs from forming on school grounds.

...Should There Be Dress Codes In Junior High And High Schools? Name: Institution: Should There Be Dress Codes In Junior High And High Schools? Introduction The dress code for junior and high schools has been a hot debate over the years. It has sought to address various issues and have resulted in different levels of controversy. For instance, in the early 1970s boys with long hair sometimes got attracted to their classmates. Resultantly, schools required young men to cut their hair short. Moreover, at the beginning of the 1990s several organizations and parents pushed for a dress code as a strategy to curb gang-related violence (Valdez, 2015). Over the years, the desire to create a professional school environment and reduce struggle over designer clothes made uniforms and dress codes become a familiar topic. However, identical strategies are more restrictive than dress code policies. Dress codes are strict as in the case of schools in California and Napa. For instance, schools in this areas required students to put on solid colors and logos or banned images on clothes. The primary objective of this argumentative essay is to provide adequate evidence that there should be dress codes in both junior and high schools. Claim 1: dress code may increase student safety and reduce crime. Each year several schools adopt a certain form of dress code. Although some challenges are emerging on the constitutionality, court’s rulings have......

Uniforms in Public Schools

...Uniforms in Public Schools Marla Downey Axia College of University of Phoenix COM 120 Effective Persuasive Writing Dr. Carla Lane February 21, 2007 Uniforms in Public Schools Think back to the age of adolescence, was there ever a comment made by other children on the way one dressed or did some teasing occur regarding the lack of current style? Was there an issue of being prejudged or stereotyped by others, including school faculty, based on the clothing one chose to wear? That was then, now remember how it felt. Times have changed and economic status plays such an important role in everyone’s lives, image how children of today feel. Social economics is a hard issue for adults to deal with and yet children are forced to deal with it on a daily basis in schools with their classmates, friends, and even their teachers. What solutions can be offered to change this bias for all children, regardless of age, race, and social status? One suggestion is to put school dress codes in place which would require school uniforms. School uniforms should be mandated in public schools because our children’s self esteem and education should not be determined by the clothes they wear. There is a nationwide campaign for the use of uniforms and the efforts are “gaining momentum”, states Susan Thomas (1994, p. 44). School systems are challenged with many issues, one being “ways to reduce competition over designer labels” (Thomas, 1994, p. 44). It is safe to say that both......
