Flux pumping Flux pumping Flux pumping is a method for magnetising superconductors to fields in excess of 15 teslas. The method can be applied to any type II superconductor and exploits a fundamental property of superconductors. That is their ability to support and maintain currents on the length scale of the superconductor. Conventional magnetic materials are magnetised on a molecular scale which means that superconductors can maintain a flux density orders of magnitude bigger than conventional materials. Flux pumping is especially significant when one bears in mind that all other methods of magnetising superconductors require application of a magnetic flux density at
Flux loop integrate the signal over a period of time to get the magnetic field at that instant (not just the change in magnetic fields). This is normally done by adding a integrator circuit which will passively integrate the electrical signal. The flux loop is common on tokamaks, magnetic mirrors, Field-reversed configurations, the Levitated dipole experiment and the polywell. In tokamaks a set of loops is used, and these are spaced slightly off-center and non-concentrically. Placing the loops intentionally asymmetrically allows the users to find the magnetic field density at different points inside the tokamak. The distance between the loops was determined
