Which of the following describes an electric motor? check all that apply. a.) changes electric energy to mechanical energy. b.) can be powered by a hand crank. c.) uses the interaction between a spinning coil of wire and magnet. d.) is found in many appliances with moving parts, like a vacuum cleaner or a blender.

A, B, C and D

Explanation:

These four options are applied to describe an electric motor.

An electric motor is a device that is used to convert electrical energy into mechanical energy. It has a core with copper winding on it that carries current and due to magnetic field generated because of it, a coupled force came into existence and allows the shaft the more.

By this mechanism electrical energy is converted in to mechanical. There are a number of devices that uses electric motor such as mixer, blenders, cooler, fan and many more.

Hand crank is used for last size motor to limit the supply of current passing through it in industries.
