Absolutely - And if one really understood what was going on, and could go round the hysteresis curve in the opposite direction then one would have a magnetic energy pump. We can do it at the thermal level. Why should we not be able to do it at the magnetic level. Couldn't it be that no one has yet worked out exactly how to bell the cat - or has the Great Maxwell promulgated a Law of the Medes and Persians? Frank
