Magnetism and its uses
... Each spinning electron causes a magnetic field to form around it. Most materials have electrons that exist in pairs that spin in opposite directions thus canceling out the magnetic field. The atoms in materials such as iron, cobalt and nickel have unpaired electrons, so the electrons' magnetic field ...
