Magnetism Quiz

What is a magnet?

• A device that emits light

• A material that attracts iron

• A tool used for cutting

• A type of musical instrument

What are some different kinds of magnets?

• Permanent magnets

• Electromagnets

• Temporary magnets

• All of the above

What are magnetic poles?

• Regions where the magnetic field is strongest

• Points where magnetic lines of force converge

• Areas with no magnetic influence

• Locations that repel all metals

A magnet pushes (repels) or pulls (attracts) on another magnet when:

• The magnets are aligned with opposite poles facing each other.

• The magnets are aligned with like poles facing each other.

• The magnets are placed far apart.

• The magnets are made of different materials.

How does magnetic force change with distance? In other words, if you increase the distance between magnets, will they attract (or repel) each other more, or less?

• The magnetic force increases with distance.

• The magnetic force decreases with distance.

• The magnetic force remains constant with distance.

• The magnetic force first increases then decreases with distance.

Now that you have seen how the stopper works, what do you think will happen when you add more magnets to the stopper?

• The stopper will become stronger.

• The stopper will become weaker.

• The stopper will remain the same.

• The stopper will stop working.

What should be on the vertical axis when creating a graph with the distance between magnets and the number of magnets?

• Distance between magnets

• Number of magnets

• Time

• Temperature

How does the distance between magnets change as you add more magnets to the stopper?

• The distance increases

• The distance decreases

• The distance remains the same

• The distance fluctuates randomly
