Would it be possible to use a
single massive (ideal) wire like 1/4 inch
in diameter with a magnet then
increase the voltage to be sensed
simply narrow the wire gradually
to like 30 AWG wire in a current loop
to act as a concentrator to boost the voltage ?
Sort of like water through a pipe
which narrows suddenly ?
Is this silly ?

It seems to me you can get considerable current
using a single heavy wire, the trick is
sensing that current which is essentially
only one loop of a coil.
