How do magnets work? Cool Experiments with Magnets

In a hard magnetic material (alloys of iron such as Alnico, some steels, neodymiumironboron, etc), most of the domains will remain aligned, so that you will be left with a strong magnet. Since the ending point is not the same as the starting point for magnetic materials, they have what is called hysteresis. Magnetic Poles. 1.

Electrons and Why Magnets Stick | 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.
