6. A steady current flows down a long cylindrical wire with radius a. Find the magnetic field, both inside and outside the wire, if (a) the current is uniformly distributed over the outside surface of the wire. (b) the current is distributed in such a way that J is proportional to s, the distance from the wire's axis.
