ATOMIC MAGNETISM. “All of the atoms in an object act like several tiny magnets. In most materials, all of these moments face random directions and they all cancel each other out, and there is a net magnetization of 0, which means the object will not be a magnet. However, when all or most of these moments align in the same direction, the entire object has a net magnetization and creates a magnetic field around itself.”
