What produces the force for the torque that turns an electric motor?
The electrical attraction of opposite charges.
The force on a current in a magnetic field.
An induced electromotive force acting on a loop of wire.
Electrical attraction to the North Pole of the magnet.

Respuesta :

The appropriate response is the last one. The electrical fascination in the North Pole of the magnet. The essential standard for all electric engines is that when a current conveying conduit cuts an attractive field, a mechanical compel is created on the transmitter relative to the rate of progress in the attractive field which makes the conveyor move.
