Transformer steel is what you want.... Available in thin sheets, high
silicon content so the resistivity is high (to reduce eddy current losses),
saturation flux is high (so you don't have to wind so many turns), etc. You
may laugh, but while you can use almost anything ferrous (iron filings and
elmer's glue was tried by one list'ite, coat hanger wire by another), the
real thing is so cheap (once you find a source), you might as well use it.
