virtual magnetic flux in an area surrounded by a loop C
where Φ is the magnetic flux in the area, λ is the penetration depth, J is the superconducting current density, μ0 is the magnetic constant and dl is a vector line element. Note 1 to entry: The fluxoid in a superconductor is quantized to a multiple of the flux quantum Φ0. Note 2 to entry: The fluxoid is sometimes used instead of the fluxon which exists far from the surface of a superconductor.
