What is electricity?
Electricity is a form of energy created when sub-atomic particles called electrons flow from place to place.
When electrons build-up on an object but cannot flow further they are called an electrical charge. This charge can be released as static electricity if touched by another object that can conduct electricity.
An electric current refers to the electrons flowing from one place to another, normally within a form of electrical circuit.
Lightning is really a very powerful and natural electric "spark" caused by thunderstorms. Electrical charges build up around thunderclouds until they can be released, either between clouds, or between clouds and the ground. When that happens, a sudden and quick electric current flows, resulting in a brilliant light flashing across the sky.
Electricity can be made when a wire is moved through a magnetic field.
By winding the wire into a coil it can increase the amount of force which pushes electricity through the wire. This force is called voltage.
Both ends of the wire need to be attached to a circuit.
When the coil of wire is rotated within the magnetic field, free electrons run through the coil and around the circuit.
A coil of wire moved within a magnetic field causes electrons in the wire to move.
When the wire is connected to an electric circuit, the electrons will be under pressure to move in a certain direction causing an electric current to flow.
