Horseshoe magnet. Iron pins being temporarily magnetised by a permanent iron magnet in a horseshoe shape. 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. The pins lose their magnetism when they are removed from the presence of the permanent magnet.
