Jul 1 at 23:10	comment	added	Yukterez		@peterh - are you sure your source was talking about a nonrotating magnet? to me that sounds like the normal description of the electric and in case of rotation magnetic field lines, but in the context of a nonrotating magnet? From the outside perspective the nonrotating magnet should have the same effect as if the two poles were both in the center at r=0, so no net effect
