Compass Deviation

Magnets don't grow in fields, but magnetic fields are important to understand. The lesson covers the effect electricity has on magnetic fields. Scholars use a compass, magnets, and electrical wire to test magnetic fields and energy...

The compass was first used in 206 B.C., but we didn't discover magnetic poles until 1263 A.D. Presentation begins with the history of magnetism before continuing on to magnetic fields, magnetic forces, electromagnets, currents,...

All phenomena concerning magnets, their field lines and impact on objects are covered. The trivia surrounding field lines and the earth, electric charges, repulsion and attraction is plentiful. The slide show continues after twenty...

The magnets on a refrigerator are stronger than Earth's magnetic force. Watch a video that describes the fundamental force of magnetism. It relates magnetism to electricity and connects this to almost every type of electricity generator...

Your classes are sure to be attracted to the 32nd lesson in the exciting Crash Course physics series. Scholars learn the basics of magnetism and the forces created from current running through a wire. The lesson includes an application...

Historically, humans have used many methods of finding due north. Using a hands-on activity, learners create their own compasses. They then test their compasses in their neighborhood or to assist with stargazing.

A thorough investigation of magnetic levitation; this activity has four parts. First, physical scientists play with a wooden dowel and three disc magnets to review polarity and repelling action. Then they experiment with the strength of...

Eleventh graders examine the political demands put on one of four groups living in America during WWII. Each class member is asked to research and write a paper describing the homefront experience for women, Hispanics, African-Americans,...

Physical or earth science pupils prepare a magnetometer by inducing magnetism into a pair of straight pins. As the pins hang from a thread, they can be used to detect the magnetic field or poles of a magnet. They could also be used as a...

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 created...
