Problem
A student draws the magnetic field pattern for two bar magnets placed 4cm apart with their facing ends marked X and Y. In the sketch, the field lines between X and Y bow outward, do not join the two magnets, and a neutral zone appears at the midpoint. Which choice correctly identifies the polarities of ends X and Y and explains the observed pattern?
(a) X is North, Y is South; equal and opposite fields cancel at the midpoint so the lines deflect outward.
(b) X is South, Y is South; like poles attract, forcing the field lines to skirt the central region.
(c) X is North, Y is North; like poles repel, so the lines bend outward and a neutral point forms midway.
(d) X is South, Y is North; unlike poles repel, preventing the lines from joining.
