Magnetism Quiz

What causes an object to exhibit magnetic properties?

• The alignment of domains

• The color of the material

• The temperature of the object

• The size of the object

What determines how magnets interact with each other?

• The size of the magnet

• The color of the magnet

• The poles of the magnet

• The temperature of the magnet

What does a magnet become when it is broken?

• A single larger magnet.

• Two smaller magnets; both have a N and S pole

• Two smaller magnets; one is a N pole, the other is a S pole

• A single pole magnet.

What is the role of iron filings in visualizing magnetic fields?

• They change the color of the field.

• They align themselves along the magnetic field lines.

• They increase the temperature of the field.

• They decrease the weight of the field.

What do magnetic field lines indicate?

• The weight of the field.

• The shape and direction of the force.

• The color of the field.

• The temperature of the field.

What happens to the magnetic force when the magnets are further apart?

• It becomes stronger

• It becomes weaker

• It stays the same

• It disappears completely

What is the result of a strong magnetic force between two magnets?

• They repel each other

• They snap toward each other

• They lose their magnetism

• They become heavier

What can strong external magnetic fields do to a magnet?

• Strengthen it

• Weaken it

• Make it invisible

• Change its color

What is the basis for technologies like maglev trains and electric motors?

• Frictional force

• Magnetic force

• Gravitational force

• Electrical force

What can affect how magnets interact with each other?
