Sal and marie were experimenting with bar magnets in science class, picking up chains of paper clips. where should they expect the magnetic force of the bar magnet to be the strongest and pick up the most paper clips? a) at both poles b) at the south pole c) at the north pole d) in the center of the bar magnet

Option (A) is the correct answer.

Explanation:

A bar which is magnetic in nature actually has magnetic poles at its end. One end is south pole and the other one is north pole.

And it is known that opposite poles attract each other. Therefore, when north pole comes near south pole then due to force of attraction these poles are attracted towards each other.

Thus, we can conclude that at both poles they should expect the magnetic force of the bar magnet to be the strongest and pick up the most paper clips.
