An electric motor converts electric energy into mechanical energy that can be used to do work. In the experiment we first use DC current to flow through the wire. Remember that DC current flows in only one direction unless there is a switch to reverse its direction.
Lesson Summary. An electric motor is a device that turns electrical energy into motion, usually rotation. It changes electrical energy into mechanical or kinetic (movement) energy. This works using electromagnetism. A loop of wire containing a current is passed through an electromagnet's magnetic field.n electric motor contains a coil of wire (sometimes called a solenoid), that creates a magnetic field when electricity flows through it. This is collectively known as an electromagnet.
