How would you approach this particular challenge?
Magnet wire. E.g., from a MOT. Bob
I've got the current - carrying wire handled.
That'll be enamel - insulated copper, equivalent
to the magnet wire you mention. The challenge
is in sourcing some insulated iron or mild steel
that can be easily formed into a core for the
magnetic (not electrical) circuit.

Gut a busted microwave oven and rewind the transformer.

I want a longish "E" core in hopes that I could
concentrate a large amount of flux off the end
of a smallish pole piece. (Quiet, Larry)

Thanks!
