A magnet is an object that attracts certain materials. Magnets attract materials such as metal and copper. A magnet has North and South poles. A magnet is strongest at its poles. Magnets can sometimes occur in nature. The Earth itself is a magnet. Earth, like all other magnets, has North and South poles.
In order for a magnet to act, it needs to be surrounded by a magnetic field. A magnetic field is the space around a magnet that allows the magnet to act.
Another type of magnet is an electromagnet. An electromagnet is put together by curling a wire around a nail and attaching it to a battery. A scientist named Michael Faraday discovered the electromagnet.
Ben Franklin was also a scientist, but he is famous for a different reason. Ben Franklin discovered that lightning is a form of electricity. He did this by attaching a key to a kite. Then he went out in a storm and flew the kite. The key was struck by lightning, and Ben Franklin discovered lightning was a form of electricity in nature.
Magnets come in all different shapes and sizes. From bar magnets, to horseshoe magnets, to our Earth, magnets play a big role in the world we know today. Without magnets, you wouldn’t be able to do many of the things that you take for granted. We are very lucky that magnets exist in our world.
