Magnetic power generators have a small wheel in between magnets that are aligned in such a manner that they repel each other. The opposing forces of the magnets cause the wheel to have an unending rotating motion, poweri... More »

To make a temporary magnet or electromagnet, students can use an iron core, surround it with copper wire and then pass an electric current through this arrangement to magnetize the nail. When making an electromagnet for ... More »

An iron nail can be made into a magnet by wrapping it with insulated copper wire and letting low-voltage direct current run through the coil. The iron nail will become a temporary magnet. More »

A nail that is used in an electricity experiment with wire coiled around it is an example of a temporary magnet. When the electrical current is on, it acts as a magnet, but when it's off, it is no longer magnetic. More »
