Which statement best describes the function of electric motors?

The function of electric motors is best described as converting electrical energy into mechanical energy. This process is fundamental to how electric motors operate; they take electricity as input and transform it into motion, enabling a wide range of applications, from powering small devices to large machinery.

Electric motors work by employing electromagnetic principles, where current flowing through a coil generates a magnetic field that interacts with another magnetic field, causing rotational movement. This mechanical energy output is utilized in various devices and applications, such as fans, pumps, and conveyor systems.

While other statements hint at functions associated with different equipment—like measuring temperature, generating heat, or being used in refrigeration systems—they do not accurately capture the primary role of electric motors, which is to facilitate motion through the conversion of electrical input into mechanical work.
