Current-Carrying Coils In Magnetic Fields

Written for a college physics course, this midterm examination deals with electric and magnetic fields. When taking this test, learners answer multiple choice questions, solve problems, and analyze a variety of attractive diagrams....

Audio speakers, hard drives, credit cards, and even the earth use magnetic fields. While we observe the effect of magnetic fields, we can't actually see them. A viewer helps participants explore magnetic fields, some of the items that...

Class members use a compass and several points to map out the magnetic field of a magnet. Pairs trace the magnetic field lines produced by a permanent magnet by positioning the compass in numerous spots around the magnet to view the...

Have your class use compasses to try to find the magnetic field around an electric current. Groups use the same technique to visualize magnetic fields as they did in the second activity in the series, but this time, the field is...

Here are two electromagnetism homework assignments rolled into one. The first eight practice problems deal with the magnetic field and magnetic force exerted by current-carrying wires. The second set of seven problems are specific to...

After high schoolers have learned about electromagnetic induction, they can solve these 10 practice problems. They calculate magnetic field strength, magnetic force, electromotive force, and output voltage. This is a choice option as a...

Class members use mathematics in order to better understand magnetic forces and their interaction on charged particles. After a demonstration of the interaction between a magnet and an electron beam using a CRT computer monitor,...

Magnetic fields might not be a field of dreams but they are useful. Class members observe the reactions of magnetic fields using a compass, iron filings in a paper container, and iron filings suspended in mineral oil.
