Answer:
The pencil box is too far away from the magnet to make it move.
Explanation:
The most likely scenario here is that the pencil box is too far away from the magnet to make it move.
A magnet has a force field around it which dictates the region where magnetic influences can be felt when a magnetic body is brought near it.
Outside the force field, a magnet has no effect on a magnetic body.
Objects that are far away from a magnetic source will feel no effect of the force field of a bar magnet.
