Horseshoe magnet with various magnetic and non- magnetic objects. Ferrous objects such as a knife and screw are temporarily magnetised by a permanent iron magnet. An aluminium can and other non-metallic objects are left unaffected. Magnetism is mostly a property of metals. It is a force exerted at a distance through a field, generated by moving electric charge (electrons). It can attract or repel.
