Which Metals Are Magnetic? | Metal Supermarkets UK

2015-10-27 · Electromagnets. Electromagnets are made from a coil of copper wire wound around a core made from iron, nickel or cobalt. The coiled wire will generate a magnetic field when an electric current passes through it, however, the magnetic field disappears the moment the current stops. Electromagnets need electricity to work.
