An electromagnetic device used to convert electrical energy into mechanical energy is a(n):

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

Answer: (A)

The device described is a motor because it specifically turns electrical energy into mechanical energy. When current flows through the motor’s windings inside a magnetic field, electromagnetic forces produce torque that spins the shaft, converting electrical power into motion. A generator does the opposite—it uses mechanical energy to generate electrical energy. A transformer changes voltage and current but doesn’t create motion. A battery stores chemical energy and delivers electrical energy, but it doesn’t convert that energy into mechanical work by itself. Therefore, the best answer is the motor.
