All this talk of pinning is just fine, but all of this is nicely predicted by the basic laws of electrical induction and the zero resistivity offered by a superconductor, you would expect repulsion or attraction to occur.
No it is not. This flux pinning thing is a big deal. The same mechanism accounts for the pinning of flux in a superconductor accounts for the energy levels of the atom. A solution that includes both provides for a classical foundation for quantum physics. Flux is pinned in the nucleus too. An understanding of the release mechanism provides for a new understanding of the cold fusion reaction. Flux is pinned at discontinuities. It is shook free by a vibration at a dimensional frequency of 1,094,000 meters/second. Thats it. I did the experiment with the superconductor, Horace now has it. Frank Znidarsic
