... Magnetism is phenomenon that arises out of the movement of electric charge, a fundamental property of matter. It creates a magnetic force, a "push" or "pull", on objects with moving electric charge. Magnetism can also be demonstrated with a pair of magnets. Although currents, or a moving flow of ele ...

PHY 212 LAB – Magnetic Field As a Function of Current
... You’ve observed in your everyday life that magnets attract or repel. Let’s investigate. 1. Obtain a set of four neodymium magnets. We’ll treat this is a single magnetic dipole. 2. Use your compass to determine the N and S poles of your magnet. Place a large piece of Scotch tape on the N side of your ...
