magnetic flux quantum

[mag‚ned·ik ′fləks ‚kwän·təm]
(electricity)
A fundamental unit of magnetic flux, the total magnetic flux in a fluxoid in a type II superconductor, equal to h /(2 e), where h is Planck's constant and e is the magnitude of the electron charge, or approximately 2.07 × 10-15 weber.
