INSULATORS AND CONDUCTORS

An insulator is a material that does not allow electricity to flow through it easily.

A conductor is a material that allows electricity to flow through it easily.

Metal is a good conductor of electricity.

Plastic is a good insulator.

In a complete circuit, electricity can flow and power devices like light bulbs.

An electromagnet is a type of magnet that can be turned on and off using electricity.

You can turn an electromagnet on or off by controlling the flow of electricity to it.

A magnet is always magnetic, while an electromagnet can be turned on and off.

A battery provides the electrical energy needed to power the circuit.

An open circuit means that the path for electricity is broken, so electricity cannot flow.
