Hi,
Suppose I have an infinite cylinder with radius R, axis along the z axis and constant magnetization M[itex]\hat{z}[/itex]. I wish to find the magnetic field everywhere. (This is not a HW question per se, yet thought I might get some comments on my attempt at solving it nevertheless.)
As M is constant and [itex]\vec{j}[/itex] = cM[itex]\hat{θ}[/itex], i.e. tangential current, may I consider this to be an infinite solenoid, whose magnetic field is zero everywhere, except for within the solenoid where it is equal to 4πnI/c (using c.g.s), where n is the density of wraps, which is equal to 4πM (in the positive z direction)?
