1. Electromagnetic Fields

2. A magnetic field is an area where the forces of attraction from a magnet are working.
An electromagnetic field has the same effect as a magnetic field but it can be turned on and off by stopping the electricity which it requires.
Electric motors are one of the main uses of electromagnetic fields.
Electric motors convert electrical energy into mechanical energy. The mechanical energy is normally used to turn things like wheels.
A generator is like an electric motor used the other way where mechanical energy is converted to electrical energy.
Other uses of electromagnetic fields are LCD screens and electromagnetic cranes.
