O
The pencil box is too far away from the magnet to make it move.

Answer 1

The pencil box is too far away from the magnet to make it move.

Step-by-step 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.

• Since the magnet is not attracting or repelling the metallic box of pencils, they most be located outside the field of force of the magnet.
• When they are within the force field, repulsion or attraction occurs and the field draws the metal to itself or repel.

Objects that are far away from a magnetic source will feel no effect of the force field of a bar magnet.
