What is created when a magnet moves through a coil of wire?

• A. an electromagnet
• B. a ferromagnet
• C. a solenoid
• D. an electric current

What kind of magnet can be turned on and off?

• refrigerator magnet
• electromagnet
• magnetite
• iron

If you wrap more coils around an electromagnet, it will become 

• brighter
• stronger
• weaker
• invisible

The strongest parts of the magnet are ...

• fronts

• backs

• poles

• middle

What would happen is a north pole of a magnet came close to a north pole of another magnet?

• they would be attracted to each other

• they would be repelled from each other

The area around a magnet is called the .....

• attraction zone

• work area

• magnetic field

• hot zone

Why does the compass needle move at different locations?

• Because the needle is attracted to the magnetic field produced by the magnet

• Because north is up

• Because it is being attracted to the Magnetic North Pole

• Because north is down
