  • How Magnets Work | HowStuffWorks

    Iron, for example, has four unpaired electrons with the same spin. Because they have no opposing fields to cancel their effects, these electrons have an orbital magnetic moment. The magnetic moment is a vector it has a magnitude and a direction. It's related to both the magnetic field strength and the torque that the field exerts.
