The value of this quantity in an Abrikosov vortex is the winding number times hc over 2 e. In approximations to solar plasma, this quantity moves with material according to the freezing-in theorem. In the generalized form of London's second equation, a quantity with units equivalent to this is divided by two pi. This quantity is related to charge by a memristor. This entity is quantized in units of "2 n pi h-bar c over e" within a superconductor. The rate of change in this quantity in time is proportional to induced emf by Faraday's law of induction. This is the integral of B over a surface. It is measured in webers.
