According to the video, what rule helps to show the direction of the magnetic field?

• Maxwell's Corkscrew Rule

• Faraday's Law

• Fleming's Left-Hand Rule

• Ohm's Law

What happens to the magnetic fields above and below the wire?

• They both cancel out

• Above they reinforce, below they cancel

• They both reinforce each other

• Above they cancel, below they reinforce

What is the effect called when a wire is pushed out of a magnetic field?

• The Induction Effect

• The Generator Effect

• The Motor Effect

• The Transformer Effect

What happens when the current in the wire is reversed?

• The wire moves faster

• The wire remains stationary

• The force on the wire doubles

• The force on the wire reverses direction

How is circular motion achieved in the setup described?

• By using a larger magnet

• Increasing the voltage

• Decreasing the resistance

• Using a stronger magnet

What component ensures the current flows in the same direction in a spinning coil?

• A diode

• A capacitor

• A split ring commutator

• A resistor

What is the purpose of the split ring commutator in an electric motor?

• To increase the speed of the motor

• To reverse the direction of the motor

• To maintain consistent current direction

• To decrease the motor's power consumption
