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.
