Let a closed path C pass N times around a current (i.e., N is the winding number of the path around the current). Then the line integral of the magnetic field B along the path is given in cgs by
(1)

where c is the speed of light and is the differential length element. Similarly, in MKS,
(2)

where is the permeability of free space.
