Magnetism

Magnetism is a form of separating mixtures which involves using a magnet to attract another magnetic object away from the substance it is in. Some examples of separating magnetic substances from non magnetic substances are: separating iron nails from glass chippings and separating iron paper clips from brass ones.

Magnetic separators are used in factories. Materials are put on a conveyor belt that is spun by magnetic wheels. As the objects are moved upside down the non magnetic objects fall off and the magnetic ones stay on.
