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. The magnetization defines the auxiliary magnetic field H as (SI units) (Gaussian units) The behavior of magnetic fields (B, H), electric fields (E, D), charge density (ρ), and current density (J) is described by Maxwell's equations.

Current density - Wikipedia

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. The quantity in the above equation WebAug 1, 2024 · After all there is a phenomenon called circular eddy currents. Admin almost 4 years The title of the question makes it sound like you think the curl of the current density is always zero, and you want to know why. It's not always zero. It's just zero in this example (because the velocity is assumed constant). Kyle Kanos about 8 years WebIndeed, the left hand side of the curl equation ∇× B= µ0Jalways have zero divergence ∇·(∇× B) = 0, (8) so we cannot have ∇ × B= µ0Junless the RHS has zero divergence as well, ∇ ·J= 0.
