Hi Doc,

Thanks, but this I know. The problem aint that simple. OK, lets say the
wire is high carbon content steel, easily magnetised in the usual way (run
a magnet down its lenght, or whatever). Passing a pulse of current down
this wire, as far as I can tell, does not leave the wire magnetised. Is
there a way of accomplishing this? The inventor may of course be insane
(not uncommon, I hear :)

Bill.
