Uniformely magnetised cylinder

[Feynmanfan]

Dear friends,

I'm having trouble with this magnetostatics problem.

I have a uniformely magnetised finite cylinder and I'm asked to find B and H along the axis, using two different methods to get the correct answer.I believe the first one is considering magnetisation currents and the other one "magnetic charges".

I don't know if I'm doing it right when I compare this problem to the one of the finite solenoid (is it the same). What are magnetic charges?

Thanks for your help

Just give me a hint, please.

I assume "magnetic charges" is referring to the magnetic monolpole. Not sure what you will do with it, but by analogy to electric charges and polarization of dielectrics there should be a representation of magnetic dipoles as combinations of two magnetic monopoles
