=Electricity and Magnetism Review= =Test will be on Friday, October 22=

Magnets
Like poles repel and opposite poles attract. (north ↔ north) (north  south)

Magnets are attracted to objects made of iron or steel.

An induced magnet is a temporary magnet.

Magnetite contains pieces of magnetized iron.

Electricity
In a series circuit, electrons can follow only one path.

In a parallel circuit, electrons can follow two or more paths.

A D-cell is an electric source. It supplies power to a circuit.

An insulator is matter that does not allow electrons to flow freely.

A conductor is matter that allows electrons to flow freely.

To make an electromagnet stronger you can wind the wire around the core more times.

To build an electromagnet, you need a rivet, a D-cell, and wire.

A switch opens and closes a circuit.

In an open circuit, electrons cannot flow.

In a closed circuit, a circuit that is complete and electrons can flow.

Electricity and water is a bad combination.

Any metal will conduct electricity.
