1. The relation of direction of motion of the wire in a field to direction of induced emf can be determined by Fleming’s right-hand rule. 2. An alternate way of stating Lenz’s law is that an induced voltage or current opposes a change of magnetic field. 3. When mechanical energy must be expended to rotate a coil within a magnetic field and cut the lines of flux, this energy is provided by engines called flux movers. 4. Not all generators are designed to maintain coils within a magnetic field but, instead, hold a magnet within a rotating coil. 5. The induction process in rotating machines produces AC, and if direct current (DC) is needed, it can be obtained from AC by using rectifiers.
