World's Simplest Motor
Question: How does a motor work?
Safety Procedures:
Neodymium magnets are very powerful and magnetic materials snap onto them very quickly and forcefully. Be careful while handling, as finger may get pinched!
Procedure:

What Happened?
The wire spun when placed on the battery!
The permanent motor always has a magnetic field. The wire, however, does not except when it is electrified. Then the wire becomes an electromagnet which has a magnetic field. The wire's magnetic fields interact with the permanent magnet's magnetic field, and the wire spins!

Every magnet produces an invisible area of influence around itself. When things made of metal or other magnets come close to this region of space, they feel a pull or a push from the magnet. Scientists call these invisible influences FIELDS. You can make magnetic fields visible to the eye by using iron chips sprinkled on a piece of paper with a magnet underneath.
