Magnetic Field

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...

No GPS allowed! High school scientists continue to explore magnetic fields with a hands-on activity. After mapping the ambient magnetic field in the classroom and completing data analysis, they write about the similarities and...

Let this video teach the basics of magnetism for you in a flipped classroom scenario. In a six-and-a-half minute feature, physics fans find out about the intrinsic properties of magnetism and its relation to electricity.

Your advanced physics class will appreciate this instructional activity in which they use magnetic field sensors to determine the relationship between the number of turns per meter of a solenoid and the magnetic field produced. The...

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...

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...

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,...

Captivating information about how frogs can levitate in magnetic fields. Easy to understand, it also explains how the Earth's magnetic field is produced.

The earth has a giant magnetic field caused by the liquid iron that constantly moves in the outer core. Scholars explore the magnetic fields of four different planets. The strength and alignment of the poles relates to the implications...
