The baron between magnets occurs without the magnets touchi ng, it occurs at a distance. When two magnet! s attract there are in each opposites magnetic field. magnetic properties can be found in certain materials equivalent iron, cobalt and nickel. When a material has magnetic properties it is attracted to iron, iron alloys and other magnetic materials. An physical object with magnetism will make up itself to iron if placed in close proximity to it. magnetized forces are produced by a motion of charged particles ilk electrons....If you want to get a full essay, order it on our website:
