Applying this equation to one of the London equations and taking the curl gives an equation involving the London penetration depth, which is the depth a magnetic field penetrates into a superconductor.
Along with the mass and energy conservation laws and the generalized Ohm's law, this law is used to derive the Sweet-Parker reconnection model in plasmas. Applying this equation to one of the London equations and taking the curl gives an equation involving the London penetration depth, which is the depth a magnetic field penetrates into a superconductor. Applying the divergence to both sides of this equation gives the (*) continuity equation. Applying this equation to a closed path in the plane through the middle of a charging capacitor gives a nonzero result, requiring the displacement current. Like the Biot-Savart law, it can be used to find the magnetic field, but unlike the Biot-Savart law it considers current enclosed in closed loop. For 10 points, name this member of the Maxwell equations.
