... Rocks containing the mineral magnetite attract materials that contain iron and also attract or repel other magnetic rocks. The attraction or repulsion of magnetic materials is called magnetism. Magnetic rocks are known as lodestones. Magnets have the same properties as magnetic rocks. Magnets attrac ...

... – The motion of a magnet can induce current in practical ways. If a credit card has a magnet strip on its back, “swiping” the card can generate tiny currents that send information to cash registers. – A coil of wire and magnets set into motion around each other will generate currents in the wire. A ...
