| Mar 16, 2017 at 11:57 | comment | added | PhyEnthusiast | The differential form works at every point not on contours and surfaces. So if you are using the differential form, you will have to work out the curl of B at every point. | |
| Mar 13, 2017 at 15:39 | comment | added | The Photon | The two forms are mathematically equivalent according to Stokes' theorem. | |
| Mar 12, 2017 at 17:45 | comment | added | ZeroTheHero | @ThePhoton I can't see your suggestion being correct. For an infinitely long wire carrying current $I$ the $\vec B$ field at distance $\rho$ is just $\vec B=\frac{mu_0I}{2\pi \rho}\hat \phi$ and one easily verifies that $\nabla\times \vec B=0$ near that point, consistent with $\vec J=0$ near that point. Of course this is expected since $\vec\nabla\times B$ is local whereas the integral form of Ampere's law is global. | |
| Mar 12, 2017 at 16:44 | comment | added | The Photon | You can use the differential form $\vec\nabla\times{}\vec{B}=\mu_0\vec{J}$ in any geometry, and you probably do every time you use a FEM method to solve a magnetics problem. | |
