Ferromagnets and Electromagnets
... An electromagnet creates magnetism with an electric current. In later sections we explore this more quantitatively, nding the strength and direction of magnetic elds created by various currents. But what about ferromagnets? Figure 8 shows models of how electric currents create magnetism at the sub ...

... Remember the paradigm for this unit: a current-carrying wire has a magnetic field around it. A permanent magnet also has a magnetic field around it, even though no current flows through it. Clearly, a net current is not necessary for a magnetic field. What is going on? It looks like we need moving c ...
