Magneto-hydrodynamic Drives

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...

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 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...

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...

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,...

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...

Examine how a magnetic field can be created in a wire carrying current with this video. [9:41]

Help your young scientists learn which materials are affected by magnetic fields with an activity that presents the information about different types of materials — diamagnetic, paramagnetic, and ferromagnetic — and their interaction...

Learners investigate moving charges in magnetic fields. Some topics explored in the activities are Lorentz force, motion of a charge, and magnetic fields. The resource consists of video clips, lecture notes, online textbook chapters,...
