<P> A magnet is a material or object that produces a magnetic field . This magnetic field is invisible but is responsible for the most notable property of a magnet : a force that pulls on other ferromagnetic materials , such as iron , and attracts or repels other magnets . The overall strength of a magnet is measured by its magnetic moment or , alternatively , the total magnetic flux it produces . The local strength of magnetism in a material is measured by its magnetization . </P>
