What Is A Magnet?

MagnetmanA magnet is a piece of metal, ore or stone that has the power to attract or repel certain materials. Magnets occur naturally in the ground. Lodestone, which has been mined for centuries, is a magnetic stone made of iron ore. Today, magnets are made of different substances and are found in a range of shapes. The most common shapes are bar, horseshoe, button and ring. Magnets come in different sizes and strengths.

If you hold a magnet near a refrigerator door, you can feel it being pulled towards the door. This is attraction. If you let go the magnet sticks to the door. You cannot see how magnets work but you can have lots of fun using them.
