What is the primary function of an electric motor?

The primary function of an electric motor is to convert electrical energy into mechanical energy. This process is fundamental to the operation of various devices and machinery, allowing them to perform work through movement. In an electric motor, electrical energy supplied to the coils generates a magnetic field that interacts with permanent magnets, causing the motor's rotor to spin. This rotational motion can then be harnessed to drive equipment, fan blades, machinery, and many other applications.

Understanding this function highlights the role of electric motors in everyday technology; they are essential in everything from household appliances to electric vehicles. This conversion of energy is key to translating the energy provided by electricity into physical movement that can do useful work.
