What? A copper wire moving at right angles through a magnetic field creates a net drift of electrons in one direction (one end positive the opposite negative). The interaction of the magnetic field of the electron and the external magnetic field determines the direction (induced current).I believe I have that figured out Question: At the atomic level what is the mechanics behind the magnetic field of the electron in one direction moving up through the field as opposed to when the electron in the wire is moving down through the field. I can vilualize the electron as having a magnetic field which interacts with the external magnetic field to cause a net drift in one direction for a given direction i.e. up however for the net drift to reverse direction then the magnetic field of the electron must reverse. I have researched quantum mechanics spin, etc and magnetism, cannot come to any conclusion. I could theorize the electron as having magnetic poles (N/S) much like earth which causes the electron's magnetic field to switch when the copper wire is moving in the opposite direction. I would then need to understand the net magnetic field of the atom as well as the magnetic field of the electron that causes the reversal of the magnetic field of the electron.
Re: Why does the magnetic field of an electron reverse direction?
