Draw a diagram to show motor effect. Label the diagram appropriately.

The motor effect diagram is given below: 

A current-carrying wire or coil can exert a force on a permanent magnet. This is called the motor effect. The wire could also exert a force on another nearby current-carrying wire or coil. The force increases if the strength of the magnetic field and/or current increases. It is used to predict in which direction a current-carrying wire will move in a magnetic field so make sure that you revise it well. If the two ends of the wire used to make the coil were connected directly to the electricity supply, they would soon twist together, preventing the coil from turning.The angle formed between the wire and the direction of the magnetic field. (θ) The length of the wire, carrying the current, in the magnetic field.

Electric motors are found in many household devices e.g. tumble dryers, washing machines, vacuum cleaners, electric knives, food mixers, hair dryers and electric toothbrushes. A coil of wire carrying a current in a magnetic field experiences a force that tends to make it rotate.In a generator, the other cause is mechanical motion and the effect is electric current. Hence it converts mechanical energy into electrical energy. In a motor, the other cause is electric current and the effect is mechanical motion. Hence it converts electrical energy into mechanical energy.

One easy way to make the motor run faster is to add another magnet. Hold a magnet over the top of the motor while it is running. As you move the magnet closer to the spinning coil, one of two things will happen. Either the motor will stop, or it will run faster.
