I found that the surface current bound gives: \frac{\mu_oMr}3sin\theta \hat{e_\varphi} for r<R \frac{\mu_oMR^3}3\frac{1}{r^2}sin\theta \hat{e_\varphi } for r>R But i can't find a solution for the other current bound

I know this formula. I will try to find a solution and i will upload it to be able to compare...! Thanks again!

gabbagabbahey first of all, thanks a lot. And the next problem is how is the A(x) with these current bounds??

With the word strobilization I mean the \vec{M}\times \hat{n}. Sorry but my English are not so good with the physics terms.. Oh yes, i see. So the surface current bound must be: K_{b}=\frac{r}{R}sin\theta M_{o}\hat{\theta } ?

Hello gabbagabbahey, You are right about the term "bound currents". For the surface current \vec{K}_b , the normal direction \hat{n} is always vertical to the spherical surface.But how are the coordinates of \hat{n} to put them to the type of strobilization..?? Thanks a lot for your interest.

Homework Statement If the magnetization of a sphere is: \vec{M} = \hat{\phi }\frac {r}{R}sin\theta M_{o} How much are the captive streams: J_{b}=\vec{\bigtriangledown }\times \vec{M} K_{b}=\vec{M}\times \hat{n} The Attempt at a Solution I find that the first is: J_{b} = \frac...

Inside the conductor, the electric field it's zero. I think inside the cavity the field is zero And at the surface of the cavity how can I work?

Consider a, practically,infinite metallic conductor in which inside there is a spherical cavity with radial R. At the paries there is a surface allocation of electric brunt with a surface density: σ(θ)=σοcosθ . θ: polar angle at the system of spherical coordinates with the center at the center...
