If you cut a magnet in half, what happens to the poles?

• One half gets the North Pole, the other half gets the South Pole
• Both halves get only a North Pole
• Both halves get only a South Pole
• Both halves get a North pole and a South Pole

A paper clip is an example of a:

• magnetic material
• permanent magnet
• bar magnet
• insulator

An electromagnet's poles may be reversed by:

• decreasing the voltage of the coil
• increasing the number of coils
• changing the direction of current flow
• altering the material used to make the coils

How is an electromagnet different from a permanent magnet?

• An electromagnet is smaller and less powerful.
• An electromagnet's magnetism can be turned off.
• An electromagnet can be built without using metal.
• An electromagnet does not attract objects containing iron.

A simple electromagnet can be made with which of the following?

• an electric current
• a turbine and nail
• a nail, a wire, and a battery
• a compass and a battery

A magnet will pick up a nail, but not a penny because the nail

• has rust on it.
• is lighter than the penny.
• has a sharp point.
• contains iron.
