Question

Select the correct answer from each drop-down menu. A device that uses electricity and magnetism to create motion is called a _____ . In a reverse process, a device that uses motion and magnesium can be used to create _____.
1st drop down menu Motor, Magnet, or Generator.

2nd drop down menu Light, Electromagnetism, or Electricity.

Answer 1

Answer;

1st drop; Motor

2nd drop; Electricity

A device that uses electricity and magnetism to create motion is called a motor. In a reverse process, a device that uses motion and magnesium can be used to create electricity.

Explanation;

• Motors are device which use electricity and magnetism to create motion. They pass alternating current through opposing pairs of magnets to create a rotating magnetic field which creates a magnetic field in the rotor of a motor, making it to spin around.
• Electric motors work in a reverse process by using motion and magnetism to generate electricity. When a coil or loops of wire are exposed to a changing magnetic field, an electrical current arises or is induced.
