How is the rotating magnetic field in a three-phase induction motor produced?

• Using permanent magnets

• By a single coil

• Using a DC power source

• By 3 separated coils connected to different phases

What effect does the rotating magnetic field have on the rotor?

• It charges the rotor

• It causes the rotor to spin

• It stops the rotor

• It cools the rotor
