Curl of current density
Websince the curl of a gradient is automatically zero. across an irrotational vector field in physics we can always write it as the gradient of some scalar field. This is clearly a useful thing to do, since it enables us to replace a vector field by a much simpler scalar field.

We can do this is because the integral is over the primed coordinates (i.e.,r′) that specify the sources (current density), while the curl take the derivatives of the unprimed coordinates (i.e., r ) that describe the fields (magnetic flux density). Q: Yikes! That curl operation still looks particularly difficult.
WebApr 2, 2024 · The divergence of the current density is merely − d ρ / d t, so as there is charge flowing through the wire the magnitude of the current density ought to only be non-zero within the wire. The divergence of the electric field is only non-zero at point charges.

WebThe curl is the current density, and hence restricted to the region r < R, where it tends to be concentrated at the periphery. Evaluation of the curl in cylindrical coordinates gives a result consistent with this expectation. The current density and magnetic field intensity are sketched in Fig. 2.7.4.

The current density vector is defined as a vector whose magnitude is the electric current per cross-sectional area at a given point in space, its direction being that of the motion of the positive charges at this point. In SI base units, the electric current density is m… The behavior of magnetic fields (B, H), electric fields (E, D), charge density (ρ), and current density (J) is described by Maxwell's equations.
