Question

A long cylindrical shell has an inner radius a and an outer radius b and carries a current I parallel to the central axis. Assume that within the material of the shell the current density is uniformly distributed. Find the expressions for the magnitude of the magnetic field for the following. (Use the following as necessary: ??, r, a, I, ?, and b.) (a) 0 < r < a B? < ? = 0 (b) a < r < b B? < ? < ? = (??I / 2?r) * ((r² - a²) / (b² - a²)) (c) r > b B? > ? = ui
