This quantity's namesake linkage is related to the electric charge in a memristor.
For a charged particle gyrating around a guiding center, this quantity is the third adiabatic invariant. It is quantized in units of Planck's constant over twice the electron charge. In a perfectly conducting fluid, the time derivative of this quantity is zero according to Alfven's theorem. This quantity's namesake linkage is related to the electric charge in a memristor. A superconductor can be made to levitate via (*) "pinning" of this quantity. The time derivative of this quantity through a closed loop is equal to the induced emf by Faraday's Law. This quantity is zero in the absence of monopoles by Gauss's Law of magnetism. For 10 points, the SI unit Weber is used to measure what quantity, the surface integral of the magnetic field?
