6. Electromagnets are used in simple motors and circuit breakers
When an electric current flows through a coil of wire there is a magnetic field around the wire. One end of the coil becomes a north-seeking pole and the other end becomes a south-seeking pole. This is called an electromagnet.
Reversing the current in an electromagnet reverses the poles of the electromagnet.

Electric Motors
When a wire carrying an electric current is placed in a magnetic field it experiences a force. The size of the force increases with;
increasing strength of the magnetic field
increasing current
The direction of the force can be reversed by changing the direction of the current or the magnetic field
