Magnets and Electromagnets
... At the atomic level, there are protons (+ charge) & neutrons (neutral charge) in the nucleus, and electrons (- charge) spinning in orbits around the nucleus. The moving electron acts as a mini electrical charge and therefore has a magnetic field associated w/ it. In ferrous materials clusters of ato ...
