Electrical to Chemical Energy Science Project Idea

How electrical energy is changed into mechanical energy by the electric motor.A motor  by which the electrical energy developed by the dynamo is changed back into mechanical energy is really the reverse of a dynamo; a current passes both into the field magnets and the armature, resulting in a rotation of the armature, which by means of belts, etc., may set machinery in motion.The principle of the motor may be illustrated in the following way.

Motor Science Experiment

Suspend a loop or a coil of wire between the poles of a magnet.It will hang in any position in which it is placed.If now a current of electricity is passed through it, the coil, as in the case of the electric bell coil, becomes a magnet and takes a definite position with reference to the field magnets.If the current is reversed, the coil swings around 180.

The dotted line represents the position of the wire as current passes through it.The Figure represents the influence of a magnet upon a wire through which a current of electricity is passing.It can easily be understood how the armature will continue its rotation, if the current is reversed at proper intervals of time.
