Problem
Two identical bar magnets are aligned horizontally on a frictionless table with their north poles facing each other and separated by a small distance d. Point P is located exactly halfway between the two facing north poles on the line joining their centers. Which statement best describes the net magnetic field at point P?
(a) The net magnetic field points toward the midpoint because magnetic field lines enter north poles.
(b) The net magnetic field points vertically upward because the horizontal components cancel, leaving only perpendicular components.
(c) The net magnetic field is zero because the contributions from the two identical magnets cancel.
(d) The net magnetic field points away from the region between the magnets along the line because the two field contributions add.
