<P> A permanent magnet is an object made from a material that is magnetized and creates its own persistent magnetic field . An everyday example is a refrigerator magnet used to hold notes on a refrigerator door . Materials that can be magnetized , which are also the ones that are strongly attracted to a magnet , are called ferromagnetic ( or ferrimagnetic ) . These include iron , nickel , cobalt , some alloys of rare - earth metals , and some naturally occurring minerals such as lodestone . Although ferromagnetic ( and ferrimagnetic ) materials are the only ones attracted to a magnet strongly enough to be commonly considered magnetic , all other substances respond weakly to a magnetic field , by one of several other types of magnetism . </P>
