Problem
A small bar magnet at the origin experiences a 4.0N magnetic force directed due east because of a nearby magnet and a 3.0N magnetic force directed due north because of a second magnet. Ignoring all other interactions, what is the magnitude of the net magnetic force acting on the bar magnet?
(a) 12.5N
(b) 5.0N
(c) 1.0N
(d) 7.0N
