From my understanding to increase the strength of an inductor/ electromagnet you either increase the number of turns of wire or the amperage. So in theory a 5 amp electromagnet at 10 volts should have the same strength as a 5 amp electromagnet at 120 volts. Assuming that the number of turns remains the same, correct?
This brings me to my real question. Generators slow down with increased electrical load because their coils produce an opposing magnetic field which slows down the rotor with a counter torque. So why don't generators simply generate a high voltage/ low amperage output and then send that to a transformer which then lowers the voltage and increases the amperage away from the generator? Wouldn't this give you the same power that you wan't whilst producing a lower load on the generator? Perhaps this is done already or I'm misunderstanding something.
