E & M

What do the lines around this magnet represent?

• North Pole
• South Pole
• Magnetic Declination
• Magnetic Field

As the distance between two magnets increases (they get farther apart), the force between them:

• Increases
• Decreases
• Stays the Same

What kind of magnet can be turned on and off?

• refridgerator magnet
• electromagnet
• magnetite
• iron

This is a picture of a simple electromagnet. How can the electromagnet be made stronger?

• Add more coils of wire to the nail.
• Use a smaller battery.
• Reverse the poles of the magnet.
• Remove all the coils and the nail.

Unlike poles of different magnets

• attract each other

• cancel each other out

• repel each other

What is the difference between a conductor and an insulator?

• An insulator allows electricity to flow through it easily and a conductor does not
• A conductor allows electricity to flow through it easily and an insulator does not.
• An insulator is magnetic and a conductor is not
• A conductor is magnetic and an insulator is not

What will happen if one light bulb is removed from this circuit?

• The other bulbs will go out.
• The other bulbs will stay on
• The other bulbs will get dimmer.
• The battery will become stronger.

The current has only has one loop to flow through in this circuit. 

• Series Circuit 
• Parallel Circuit 

Which of the two circuits would have the brightest bulbs? 

• A
• B

What kind of circuit is this?

• Series
• Consecutive
• Parallel
• Training
