Answer: A piece of iron or another substance whose atoms are arranged in such a way as to give it magnetic qualities, such as the ability to attract other iron-containing objects or to align itself with an external magnetic field.
There are five purposes for magnets:
- A compass uses a magnet to display the direction.
- To raise objects, strong magnets are employed.
- Motors and generators both employ magnets.
- Protects a water heater from corrosion. Before reaching the heater, the magnetic calcium particles are drawn to the magnets.
- Medical equipment uses magnets.
