Homework Help: Physics

Posted by Anonymous on Wednesday, November 12, 2008 at 8:31pm.

A wire of radius R carries a non-uniform current: the current density, j, (current per unit area) varies as a function of distance r from the central axis of the wire according to j = j0(R/r) (and j = 0 outside the wire, of course). Find expressions for the strength of the magnetic field in the regions 0 < r < R and R < r.
