Which device converts electrical energy into mechanical motion?

Which device converts electrical energy into mechanical motion?

• A. Motor
• B. Solenoid
• C. Transformer
• D. Electromagnetic Actuator

Answer: (D)

An actuator is a device that turns electrical energy into motion, using electromagnetic forces to move something. The broad term electromagnetic actuator fits this idea exactly: it denotes any device that converts electrical energy into mechanical motion, whether it produces rotation (like a motor) or linear movement (like a solenoid). A transformer doesn’t create motion at all; it merely transfers energy between circuits by changing voltage and current. So the term that best captures the conversion from electrical energy to mechanical motion in a single label is electromagnetic actuator.
