Which device converts electrical energy into mechanical energy?

Which device converts electrical energy into mechanical energy?

• A. Electric Generator
• B. Electric Motor
• C. Transformer
• D. Battery

Answer: (B)

An electric motor is the device that converts electrical energy into mechanical energy. When electricity flows through the motor’s windings, it creates a magnetic field. This field interacts with permanent magnets or other magnetic structures inside the motor, producing torque that makes the rotor turn. That rotational motion is the mechanical energy the motor provides, which can drive fans, wheels, drills, and many other machines. Other devices do different energy conversions. A generator turns mechanical energy into electrical energy. A transformer moves electrical energy between voltages without creating mechanical work. A battery stores chemical energy and supplies electrical energy when connected in a circuit, but it doesn’t by itself convert electrical energy into motion.
