Magnetic field due to a solid wire of current using Ampere's circuital law. Current flows with density [tex]J=J_{o}\frac{U}{r}a_{z}[/tex] [A/m^2] along long solid cylindrical wire of radius a having the z-axis as its axis. Find H(adsbygoogle = window.adsbygoogle || []).push({});

[tex]\oint_{c}H\cdot\,dl=\int_{s}J\cdot\,dS[/tex]

Am I on the right way to solution?

[tex]\int_{s}J\cdot\,dS =[/tex]

[tex]=\int_{r=0}^{r} \int_{\Phi}^{2\pi}J_{o}\frac{U}{r}a_{z}\cdot\ r \ dr\, d\phi\,a_{z}[/tex]

Thank You very much for any help?
