Sorry, but I think your explanation of diamagnetism (repelling a
grape; love that!) as a consequence of Lenz's Law is not correct.
If it were true, surely copper and aluminum would be repelled. (Not
sure they aren't, but I don't think so.) Diamagnetism doesn't
require a changing field, afaik.
Nevertheless, you have a peachy collection of experiments.
