c. A galvanometer
d. A motor
e. None of the above.

2. What are the opposite ends of a magnet called?
a. Its terminals
b. Its north and south poles
c. Its magnetic fields
d. Its electromagnetic poles
e. None of the above

3. How are electrical charges and magnetic poles similar?

a. Unlike attract and the same type repel
b. Both are plus and minus
c. Magnetic poles attract electrons
d. Both change positive to negative charges
e. None of the above

4. What can iron filings sprinkled on a piece of paper show you?
a. That current can flow through the filings
b. That paper distorts magnetism
c. That magnetic fields are counter clockwise
d. The pattern of a magnetic force field
e. None of the above

5. How can you show that electricity creates a magnetic field?

a. Use a compass near a wire with current
        flowing through it
b. Only magnets create magnetic fields
c. Move a wire through a magnetic field
d. Connect a battery to the magnetic field
e. None of the above

6. How do you make an electromagnet?
a. Attach a natural magnet to a battery
b. Run current through a wire wrapped around
        an iron rod
c. Line up the N and S poles of a magnet with
        an electric wire
d. Wrap a magnet around a piece of wire with
        current flowing through it.
e. None of the above

7. What happens when you turn off the current in an
    electromagnet?
a. The magnetism is turned off
b. The current keeps flowing because of the
         magnetic force
c. The electromagnet reverses its polarity
d. The electromagnet becomes a generator
e. None of the above

8. How can you create electricity with a magnet?
a. Attach a magnet to a battery
b. By putting a current through a wire around
        a magnet
c. By moving a wire through a magnetic field
d. You can't, because only friction on electric
        charges creates electricity
e. None of the above

9. What would happen if you spun the rotor of an electric motor?
a. The motor would become an electromagnet
b. Nothing, because you need electricity to
        spin it
c. You would heat up the coils
d. You would create electricity
e. None of the above

10. Can you create electricity with a magnet?
a. No, because only friction on electric
        charges or batteries create electricity.
b. Yes, by moving a wire through a magnetic
         field
c. Yes, by putting a current through a wire
         around a magnet
d. Yes because magnets use electricity
         to stay effective
e. None of the above.
