An electromagnet is a magnet that relies on an electric current to produce the magnetic field. ... By wrapping the wire into a coil, the magnetic field becomes stronger in the center of the coil. The addition of a ferromagnetic core in the center of the coil dramatically increases the strength of the magnetic field.
