virtual magnetic flux in an area surrounded by a loop C where is the magnetic flux in the area, is the London penetration depth, is the superconducting current density, is the magnetic constant and is a vector line element
Note 1 to entry: The fluxoid in a superconductor is quantized to a multiple of the flux quantum . Note 2 to entry: The fluxoid is sometimes used instead of the fluxon, which exists far from the surface of a superconductor. Note 3 to entry: This entry was numbered 815-10-15 in IEC 60050-815:2015. |
