(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

If the magnetization of a sphere is:

[tex]\vec{M} = \hat{\phi }\frac {r}{R}sin\theta M_{o}[/tex]

How much are the captive streams:

[tex]J_{b}=\vec{\bigtriangledown }\times \vec{M}[/tex]

[tex]K_{b}=\vec{M}\times \hat{n}[/tex]

3. The attempt at a solution

I find that the first is:

[tex]J_{b} = \frac {2M_{o}}{R}(cos\theta \hat{r} - sin\theta \hat{\theta })[/tex]

but i don't know if that is correct and the point that i really want help is how to work the K.

Thank you a lot.
