Current density
In electromagnetism, current density is the electric current (or 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 current density at a given point in space and whose direction is that of the motion of the positive charges at this point. In SI base units, the electric current density is measured in amperes per meter square.
