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
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...
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 teh system of spherical coordinates with the center at the center...
