A form of this law states that the vector potential at a field point is equal to the magnetic constant times the source-space integral of the source current density divided by the distance between source and field points. Taking the curl of this and specifying a line current distribution yields the familiar form dB = μ0/4π I dl × r/r2 [D B equals mu naught over four pi times I D L cross R divided by R squared], which gives the differential magnetic field from a differential element of current. For 10 points, name this law from magnetostatics, the magnetic analog of Coulomb's law, which is named for its two French discoverers.
