Claim B: More potential energy can be stored by moving against the magnetic force closer to a magnet. Describe the tests you conducted and the evidence you found to support or refute this claim.

Here's link to the

claim A: definitely  because, There is more potential energy when a magnet moves AGAINST (opposite direction from) a magnetic force. ... All objects have a gravitational force, no matter how small, but only some objects such as iron objects can have a magnetic force.      

claim B: definitely not because for you  put it closer the less potential energy it has

Explanation:

hope i am right and also, hope i help :)
