Solenoid

How is energy output shown in this diagram?

• by the galvanometer at the bottom of the diagram detecting electric current produced

• by the rings and brushes attached to the solenoid that cause the movement of the solenoid

• by the permanent magnet

• by the motion of the solenoid coil

Motor or Generator?

• Motor: mechanical energy that turns the solenoid is converted to electrical energy in the lightbulb

• Generator: mechanical energy that turns the solenoid is converted to electrical energy in the lightbulb

• Motor: electrical energy from the lightbulb is converted to mechanical energy in the solenoid

• Generator: electrical energy from the lightbulb is converted to mechanical energy in the solenoid.
