Question
1. A steady current I flows down a long cylindrical wire of radius a. Find the magnetic
freld, both inside and outside the wire, if (a) the current is uniformly distributed over the
outer surface of the wire and (b) the current is distributed in such a way that J is
proportional to the distance to the axis
