Musing about Rectangular Bar Magnets
(This is the third post in a three-part series about electrostatic and magnetostatic problems involving sharp edges.) In the first blog post of this series, we looked at magnetic field configurations of piecewise straight wires. In the second post, we discussed charged cubes and orbits of test particles in their electric field. Today we will look at magnetic systems, concretely, mainly at a rectangular bar magnet with uniform magnetization.
