A student placed these two horseshoe magnets near each other on a table.

What will happen when she lets go of the two magnets?

• One side of the magnet will repel and the other side will attract

• The two magnets will repel and push apart

• The two magnets will attract and stick together

• The force will be cancelled between the magnets

Magnetism is a

• form of energy

• force

• form of matter

• form of light

What is a magnetic field?

• an area surrounding magnetic material where magnetic forces occur

• a core area inside a magnetic material

• a collection of several similar magnetic materials

• an electrically charged object

Which of the following will NOT increase the strength of an electromagnet?

• increasing the number of coils

• increasing the electrical current in the wire

• increasing the space between coils

• using a stronger magnet in the middle

Three bar magnets are held together as you see above. What are the magnets going to look like when they are released?

Scientists have created trains that use magnets to make the trains float above the tracks as they travel. These trains float because

• the track is waxed

• the like poles repel

• the train has low density

• a chemical change occurs
