Definition: | virtual magnetic flux in an area surrounded by a loop C
${\Phi}_{\text{C}}=\Phi +{\mu}_{0}\text{\hspace{0.17em}}{\lambda}^{2}{\displaystyle \underset{\text{C}}{\int}J\cdot \mathrm{d}l}$ where μ_{0} is the magnetic constant and d is a vector line element.lNote 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. | ||

${\Phi}_{\text{C}}=\Phi +{\mu}_{0}\text{\hspace{0.17em}}{\lambda}^{2}{\displaystyle \underset{\text{C}}{\int}J\cdot \mathrm{d}l}$

where *Φ* is the magnetic flux in the area, *λ* is the penetration depth, ** J** is the superconducting current density,

Note 1 to entry: The fluxoid in a superconductor is quantized to a multiple of the flux quantum *Φ*_{0}.

Note 2 to entry: The fluxoid is sometimes used instead of the fluxon which exists far from the surface of a superconductor.
