... The coil of an ac motor has a resistance of 4.1 ohms. The motor is plugged into an outlet where the voltage is 120.0 volts (rms), and the coil develops a back emf of 118.0 volts (rms) when rotating at normal speed. The motor is turning a wheel. Find (a) the current when the motor first starts up and ...

... There are two types of poles – N pole and S pole. Each magnet has (at least) one N pole and one S pole – it is impossible for a magnet to have only one pole. The two poles are near the ends but inside the magnet. The magnetic interaction is very weak (or zero) at the midpoint between the two poles. ...
