Is the coil an electromagnet?
Since the electrons all move through the wire in one direction, there is a well-defined magnetic field surrounding the wire.
What force makes the coil spin?
A coil of wire becomes an electromagnet when current passes through it. The electromagnet interacts with a permanent magnet, causing the coil to spin.
Can you make the motor turn to the opposite direction? If so, how?
Yeah, In order to reverse the direction of an AC motor, the magnetic fields must be altered to provoke movement in the opposite direction. Since each wire consists of a positive and negative current within the magnetic fields, the flip-flopping of main and starter wires causes the motor to run in reverse rotation.
What type of energy is the input to the motor? What type of energy is the output from the motor?
The left end of the arrow represents the electrical input and the right end the mechanical output respectively.
