Question

An electric motor converts

• A. Chemical energy into electrical energy
• B. Electrical energy into mechanical energy
• C. Mechanical energy into electrical energy
• D. Electrical energy into chemical energy

Hint:

Don't confuse an electric motor with an electric generator. A generator does the opposite: it converts mechanical energy into electrical energy. A battery converts chemical energy into electrical energy.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
The question asks about the energy conversion that takes place in an electric motor. An electric motor is a device designed to produce motion.

Step 2: Detailed Explanation:
An electric motor operates on the principle that a current-carrying conductor placed in a magnetic field experiences a force.
It takes electrical energy from a source (like a battery or mains supply) and uses it to create a rotating magnetic field or to pass a current through a coil in a static magnetic field.
This process generates a torque on a rotor, causing it to spin. The spinning of the rotor is a form of mechanical energy (rotational kinetic energy).
Therefore, the net energy conversion is from electrical energy to mechanical energy.

Step 3: Final Answer:
An electric motor converts electrical energy into mechanical energy.
