I was thinking along the lines of a traditional valve that was used as the
center shaft in the electromagnet. Valves themselves seem to be light enough,
so in theory if you mounted a coil around the valve stem, I would think that
your moving mass would only be a couple of grams (the weight of the valve).

A complex system that does not work is invariably found to have
evolved from a simpler system that worked just fine.
