When this law is applied to the second London equation, the result is a quantity that is the distance in which the magnetic field of a superconductor becomes e times weaker; that is the London penetration depth.
When this law is applied to the second London equation, the result is a quantity that is the distance in which the magnetic field of a superconductor becomes e times weaker; that is the London penetration depth. If the appropriate symmetry exists in a circuit, then one can use this law in place of the Biot-Savart law. The original formulation of this law only applied to time-independent currents; however, James Maxwell added a term to this equation which corrected for time-varying electric fields, sometimes dubbed the "displacement current." Identify this basic law of electromagnetism, which relates the line integral of the magnetic field to the enclosed current times the permeability constant, named for a Frenchman.
