Horseshoe magnet. Silhouette of paperclips 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 paperclips lose their magnetism when they are removed from the presence of the permanent magnet | |
