Magnetism Quiz

Earth acts like a giant magnet because its center is made up MOSTLY of

• iron

• nickel

• cobalt

• copper

Where is the strongest attraction force of the magnet?

• at the poles

• in the middle

• at the edges

• on the surface

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

• decreases

• increases

• stays the same

• doubles

If you cut a magnet in half, what happens to the poles?

• Both halves get a North pole and a South Pole

• One half gets both poles, the other gets none

• The poles disappear

• The poles switch places

The two poles on a magnet are

• south and north

• east and west

• top and bottom

• left and right

What will happen when these magnets are brought close together?

• They will repel each other.

• They will attract each other.

• They will have no effect.

• They will rotate.

Iron, Nickel and cobalt are all _________________ materials

• magnetic

• non-magnetic

• conductive

• insulating

How can you create a temporary magnet?

• rub a magnet along a piece of iron

• heat the iron

• cool the iron

• bend the iron

Where is the force of attraction the strongest on a magnet?

• at the poles

• in the center

• on the surface

• at the edges

The entire region surrounding a magnet is known as the:

• Magnetic Field

• Electric Field

• Gravitational Field

• Radiation Zone
