Motor effect

The video explains how a magnetic field is generated when current flows through a wire. This field interacts with another magnetic field to create movement, a principle known as the motor effect. Electric motors utilize this effect to achieve continuous rotation, which is applied in various devices such as fans and electric vehicles.

What happens when a current flows through a wire?

• It produces light.

• It stops the flow of electricity.

• It generates heat.

• It creates a magnetic field.

How do two magnetic fields interact in the context of the motor effect?

• They create sound.

• They produce movement.

• They increase resistance.

• They cancel each other out.

What is the primary function of electric motors using the motor effect?

• To generate electricity.

• To produce continuous rotation.

• To store energy.

• To reduce friction.

Which of the following is an application of the motor effect?

• Hydroelectric dams

• Wind turbines

• Electric vehicles

• Solar panels

What is a common device that uses the motor effect?

• A light bulb

• A fan

• A battery

• A resistor
