Magnetism is probably something we don't spend much time thinking about, but as Schreiber points out it can fight the force of gravity and this powerful, invisible force is all around us. Magnetism was discovered by a Turkish shepherd named Magnes more than two thousand years ago, and for hundred of years it was more of a curiosity than a useful force. Today magnetism is used in doorbells, can openers, radios, refrigerators, computers and many other items in our homes. Readers will learn about the properties of magnetic materials, different types of magnets, and how a magnetic material that does not exhibit magnetic properties can be made into a magnet. Illustrations help explain the principles and walk kids through the activities. They will probably be amazed to learn that the earth itself is a giant magnet. "Scientists believe that some migratory animals use magnetite (which many animals and humans have in their brains) to find north and south.
