Question

magnetic force and energy
you may use magnets to display notes or pictures on the door of the refrigerator. a magnet attracts iron and materials that contain iron. magnets can be any size, from the ones you use in the kitchen to the entire earth and beyond. people can use magnetic compasses in navigation because the whole planet acts as a magnet (figure 1).
magnets attract iron and some other materials—usually metals. they attract or repel other magnets. this attraction or repulsion is called magnetism. the interaction between a magnet and a substance containing iron is always an attraction. magnets themselves can either attract or repel one another, depending on how they are placed.
magnetism can be a permanent or temporary property of a material. some materials, containing iron or certain other metals, can become permanent magnets after interacting with other magnets. on the other hand, temporary magnetism can occur in different ways. an iron or steel object that is touching a magnet can become a magnet itself as long as the contact exists. for example, you can make a chain of paper clips that hangs from a permanent magnet. another type of temporary magnet is created when an electric current flows through a conductor. this kind of magnet exists as long as the current is flowing.
