If the metal boxes pictured below is the same as those in the attachment and the choices given were the following:
A. The magnetic force will be the strongest on box #2
B. The magnetic force will be the weakest on box #3
C. The magnetic force will be the strongest on box #1
D. The magnetic force will be the weakest on box #1
My answer is:
C. THE MAGNETIC FORCE WILL BE THE STRONGEST ON BOX #1.
Magnetic force in North and South ends of the magnet are equal in force. It is weak in the middle part of the magnet bar. Magnetic pull is stronger on object nearest to the magnet and weaker on object far from it.
