magnetic flux quantum

The Magnetic Flux Quantum is 2.06783376 x 10 ^-15 Wb (webers). The Magnetic Flux Quantum is the quantum of magnetic flux passing through a superconducting loop.   It is a property of a supercurrent (superconducting electrical current) that the magnetic flux passing through any area bounded by such a current is quantized. The quantum of magnetic flux is a physical constant, as it is independent of the underlying material as long as it is a superconductor. The SI unit for the magnetic flux quantum is the weber.
