Hello J Bramer: Electrical charge and magnetism represent different forms of the same fundamental force or energy. Whenever an electric charge moves (and thus becomes an electric current), it causes (induces) a magnetic field around itself. Similarly, whenever an electric conductor such as copper or silver moves in a magnetic field, the electrons in the conductor shift or flow, in other words, an electric current is induced. Electromagnetism is one of the four fundamental forces of the universe; the other three are the "strong" and "weak" nuclear forces that hold an atomic nucleus together, and gravity. One of Einstein's lifelong dreams was to demonstrate mathematically that gravity and electromagnetism are different forms of the same fundamental force, just as he showed with his famous equation E = mc2 that energy and mass are equivalent. Mathematicians have recently demonstrated that electromagnetism and the weak force are different manifestations of the same fundamental force, now called the "electroweak force." Electron motion due to a magnetic field can be explained as a vector resulting from the rotation direction and the orientation of the flux field.
