Running electricity through a coil of metal wire produces a magnetic field.
Take insulated wire and wrap spirally it around a solid piece of iron (like a nail). Strip the ends of the wire and touch them to the + and – ends of a D Cell battery. The nail will become magnetic.
if you pass electricity in a coil that wraps a nail (or any ferromagnetic material) the running electrons on the wire makes a 90 degree angle electromagnetic field. This field rearranges the electrons and protons on the material making the protons go on one side and the electrons go on the other side of the nail. this helps the nail to keep its magnetic abilities.
