Section 3
Electromagnetic induction is when we use a magnetic field to produce a voltage by using a coil in a closed circuit, a current. It produces a voltage across the conductor.

Electric Motors, Generators and Transformers
Electric motors convert electrical energy into mechanical energy. The electric field and the current generate the force. The generator creates the current, transformers convert current and voltage.

Magnets work because of the magnetic field, this field surround both poles and is strongest at the poles. Electric charge in movement.

AC generators alternate the current that reverses the direction, while DC flows in one direction. They both use induction for electricity.
