Some magnets … WebHow a permanent magnet works is all to do with its atomic structure Ferromagnetic materials, the material that all magnets are made of (metals like iron, nickel and cobalt) have some unpaired electrons in their atoms. These electrons are always spinning and create their own magnetic field, albeit a very weak one.
WebMagnets are objects, which can attract, or pull, on some metals, like iron and steel. If you rub a piece of steel with a strong magnet, the piece of steel will become a magnet too. It has become magnetized. Other metals, like copper or gold, are not attracted to magnets.
