Original poster: "by way of Terry Fritz <twftesla-at-uswest-dot-net>" <ANTarchimedes-at-aol-dot-com> What would happen if you were to add a secondary? That is, wrap another tight coil around the primary with the same number of loops as the inner secondary. Then, attach the two together? Would that magnify it? Or would the induction cancel itself out, causing a loss of output?
