In electromagnetism, current density is the amount of charge per unit time that flows through a unit area of a chosen cross section. 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. The role of the magnetization is described below.

"Webcurl, and then we integrate. 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. " - Curl of current density
