Many people connect magnets in their minds to tiny items on a refrigerator or whiteboard, the guts of a compass, or perhaps a giant, red, horseshoe-shaped object used in cartoons. Many of us don’t know what makes up magnetic fields, or why they work, and believe that magnetism does not affect our daily lives.

What is a Magnet?
The word “magnet” comes to us from the ancient Greeks, who were aware of the basic properties of magnetic stones as far back as about 600 B.C. Legend attributes the name to Magnes, a shepherd whose metal staff struck the first such stone, but in truth, it probably came from a city in Asia Minor famous for magnetic minerals. A magnet is any object that generates a magnetic field. Each magnet has a north pole and a south pole of its own, just like Earth. Magnets attract iron and other ferrous metals. They can be used for compasses because if it is put in an appropriate setting and allowed to move freely, a lightweight magnet will point toward the North Pole.
