Jazelle has five different-sized magnets. She puts each magnet far away from a paper clip and slowly moves it closer until it attracts the paper clip. She records the distance between the magnet and the paper clip when it attracts. What is Jazelle's experiment designed to test?

A. how the type of paper clip affects the way in which it reacts to the force of a magnet
B. how the size of a paperclip affects the strength of its magnetic pull on objects
C. how the size of a magnet affects the strength of its magnetic pull on objects
D. how the magnetic force of a magnet affects the movement of an object

"Magnetic force" is inversely proportional to distance squared. This is also related to the size of a magnet. The bigger the size, the bigger the domain it occupies and the stronger the magnetic field. However, this is not often the case and it largely depends on the types of magnets.

In the situation above, Jazelle wanted to determine how her five different-sized magnet affect the strength of their magnetic pull on the paper clips. In order to do this, she tried to measure the distance. The closer the distance, the higher the magnetic field and the stronger the strength. The farther the distance, the lower the magnetic field and the weaker the strength.

So, this explains the answer.
