I suppose a 10Hz coil could be an interesting group project at some
time :) Getting the Q up would be interesting. One skip depth in
copper at 10 Hz implies the use of a secondary conductor that is 60
odd mm in diameter if the 3-skin depth rule is used. Then of course,
the capacitance would be humungous because the coil would have to be
huge to get the inductance which implies the output of a national
grid to run it :) :) Sounds like my kind of coil :)
