Wires moving in a magnetic field generate a current. In the case of a motor the power is coming from the electrical supply (e.g. wall socket). What I'm missing is since the wires already have a lot of current from the power supply the induced current from the magnets is probably low. Also, it...

"Is sending power the same as sending electrons? Can't you send power with an AC current?" I'm talking about the motor being also a generator. when the motor is running is it also generating a little electricity since it is a set of coils spinning in a magnetic field? The answer seems like...

Simon - thanks for taking the time. Consider me dense, but I don't understand your comments. Could you elaborate? The teacher did not discuss whether it was a DC or AC device. Does it matter with regards to the question? Thanks - Lori

Homework Statement Both an electric motor and a generator consists of coils of wires on a rotor spinning in a magnetic field. The difference is whether you desire mechanical or electrical energy as the product. If current is generated when the rotor is made to spin by either the mechanical...
