Electricity and Magnetism Post Test Review

The area around a charge where the electric force is experienced is the

• Electric Charge

• Electric Force

• Electric Field

• Electric Current

Electromagnet. The battery is not attached the paper clips falls. Why is the battery needed to pick up the paper clips?

• With the battery, the magnetic field breaks down

• It makes the nail non-magnetic

• It provides the energy needed to make an electromagnet

• It forms an incomplete circuit

Why does the light go off when a person switches off a lamp?

• Opens the electric circuit

• Completes the electrical circuit

• Completes the electrical circuit

Which magnet would be attracted to this magnet(south pole side)?

• 
• 

Which magnet would repel this magnet (north pole side)?

• 
• 

Looking at the data table, why is the electromagnet able to pick up more paper clips?

• The number of wire wraps went down

• Different types of paper clips are used

• The number of wire wraps went up

• Different types of batteries are used

How do we know that the electromagnet puts a force on the paper clips, even though they are not touching each other?

• The paperclips do not move

• The paperclips moves toward the electromagnet and sticks to it.

• The paperclips moves away from the electromagnet and repels

On a string of lights, if one light bulb burns out, none of the other lights would work. What type of circuit is this?

• A series circuit

• A parallel circuit

You can turn off your television set but all of your other appliances will stay on. What type of circuit?

• A parallel circuit

• An open circuit

• A series circuit

When the south pole is facing the south pole the magnets would...

• Attract
