Question 14 • Physical Science

Based on illustrations of magnetic field lines, where could an object be placed so it would not experience a magnetic force?

Answer
A
halfway between the like poles of two magnets, because the field lines bend away and do not enter this area
B
above the middle of a bar magnet, because the magnetic field lines are only found around the sides of the magnet
C
halfway between the opposite poles of two magnets, because the field lines are the closest together
D
above a pole of a bar magnet, because the magnetic field lines either go in or go out at the end

Explanation

Between like poles, the magnetic fields from the two magnets point in opposite directions. At the midpoint, they can cancel, making the net magnetic field zero, so an object there would not experience a magnetic force. The field lines may bend away from this region, but that does not mean the field is absent everywhere between opposite poles.
