Science Kids: Physics Videos: Learn About Magnetic Fields

Scientists need to figure out how to measure interplanetary magnetic fields, but the magnetic field of the spacecraft is interfering with their readings. Scholars attempt to solve the problem that has perplexed NASA scientists for years.

What do magnetic fields look like? The best way to learn about magnetic fields is to try identifying them for yourself. Scholars will understand the importance of magnetic fields after completing this experiment. The extension activities...

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...

It is true that Earth has a magnetic field, but do human bodies detect it? Part of a larger series, an interesting video lesson describes an experiment that attempts to answer the question. Using brain scans while exposed to a simulation...

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...

Iron filings are suspended in a bottle of baby oil and then a magnet is held up to it to bring the magnetic field to view. The remainder of this homemade video gives the instructions for making this 3-D magnetic viewing cell from common...

A large magnet is inserted into a tank of floating iron filings to reveal the magnetic field. Use this to show the shape of a magnetic field as well as how its strength appears to decrease the farther away from the magnet. The video is...

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...

A young boy, "Science Ben," smiles and follows the directions of the narrator as he traces the path of a magnetic field with a magnet. This is a demonstrative video that helps young physical scientists visualize the magnetic field. Show...
