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.

Φ est le flux magnétique à travers la surface, λ la profondeur de pénétration, J la densité de courant supraconducteur, μ0 la constante magnétique et dl un élément vectoriel d'arc

Note 1 à l’article: Le fluxoïde dans un supraconducteur est un multiple du quantum de flux Φ0.

Note 2 à l’article: Le fluxoïde est parfois utilisé à la place du fluxon qui est loin de la surface d’un supraconducteur.
