Problems in Magnetostatics 8th February 2007 Some of the later problems are quite challenging. This is characteristic of problems in magnetism. There are trivial problems and there are tough problems. Very few problems lie in between. 1. Which of these Magnetic fields can exist? Determine the current density thatcreated the valid fields. What Vector Potential corresponds to these fields? 1

2. The following current densities are given. Determine the Magnetic Fields.(a)j(r) =re-rˆθ: (b)j(r)is a square of current of 1 Ampere with its sides along thezaxis, theyaxis,y=1 andz=1. The current is flowing along 2
