Understanding Electric Motors

What is the primary function of an electric motor?

• To convert mechanical energy into electrical energy

• To store electrical energy

• To convert electrical energy into mechanical energy

• To generate electricity

Which interaction is crucial for the functioning of an electric motor?

• Thermal interaction

• Electromagnetic interaction

• Chemical interaction

• Nuclear interaction

What role does the magnetic field play in an electric motor?

• It stores energy

• It cools down the motor

• It interacts with the electric current to produce motion

• It opposes the electric current

How does a closed-loop circuit contribute to the motor's function?

• It stores electrical energy for later use

• It creates a magnetic field that opposes the magnet's field, causing motion

• It prevents the motor from overheating

• It reduces the motor's efficiency

What happens when the paperclip and wire are connected to the battery?

• The circuit remains open

• The battery discharges completely

• A closed-loop circuit is formed, allowing current to flow

• The motor stops functioning
