8.6 Electricity and Magnetism Review

Front

What is a conductor?

Back

A material that allows electrons to flow easily through it, enabling the conduction of electricity.

Front

What happens when a bar magnet is broken?

Back

Both pieces will have north and south poles.

Front

How does a magnet pick up bits of metal without touching them?

Back

There is an invisible magnetic field around the magnet.

Front

Where is a magnetic field strongest?

Back

At the poles of the magnet.

Front

What is voltage?

Back

Voltage is the measure of electric potential energy that causes current to flow from higher to lower potential energy.

Front

What is an insulator?

Back

A material that does not allow electrons to flow easily through it, preventing the conduction of electricity.

Front

What is a magnetic field?

Back

An area around a magnet where magnetic forces can be detected.

Front

What is the relationship between current and voltage in a circuit?

Back

Current flows in a circuit due to the presence of voltage, which drives the flow from higher to lower potential.

Front

What are the two types of electric current?

Back

Direct current (DC) and alternating current (AC).

Front

What is the role of a switch in an electric circuit?

Back

A switch controls the flow of current by opening or closing the circuit.
