A magnetic field H is expelled from the interior of a metal becoming superconducting [1]. Everybody thinks the phenomenon is perfectly well understood, particularly scientists with the highest H-index think that. I don’t. I am convinced that without Holes, the little fiends that Werner Heisenberg conceptualized in 1931 [2], fifty years after Edwin Hall had first detected them in some metals, you can’t understand magnetic field expulsion nor anything else about superconductivity...
