Which material is used to make a permanent magnet and also a temporary magnet?
Iron is the basic material that can be made to be either permanent or temporary . Soft iron is temporary – there are very few carbon atoms in the metal so it is virtually pure iron – so the domains are free to move easily . Steel is an alloy of iron and carbon – the carbon atoms hold the domains in position after the magnetic influence has been removed so the magnetism is “permanent”.
