magnet [%PREMIUM_LINK%] (māg'nĭt) Pronunciation Key |
A material or object that produces a magnetic field. Lodestones are natural magnets, though many materials, especially metals, can be made into magnets by exposing them to a magnetic field. See also electromagnet, ferromagnetism, magnetic pole. See Note at magnetism.
An object that attracts iron and some other materials. Magnets are said to generate a magnetic field around themselves. Every magnet has two poles, called the north and south poles. Magnetic poles exert forces on each other in such a way that like poles repel and unlike poles attract each other. A compass is a small magnet that is affected by the magnetic field of the Earth in such a way that it points to a magnetic pole of the Earth. (See magnetic field and magnetism.)
