WebThen consider what this value approaches as your region shrinks around a point. In formulas, this gives us the definition of two-dimensional curl as follows: 2d-curl F ( x, y) = lim ⁡ A ( x, y) → 0 ( 1 ∣ A ( x, y) ∣ ∮ C F ⋅ d r) … 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.
