Hi Malcolm,

Where can you get Silicon steel?? Do they make welding rods out of this stuff or is there another alloy that would work?? and what diameter rod should we be looking for??

Hi Paul,
          Whatever rods you purchase for the core, they have to have
a very small x-sectional area. They should also not retain much if
any magnetism after being de-energized (check with a magnet) or they
will have large hysteresis losses resulting in lots of heating.
Silicon steel such as used in transformer cores is preferred if you
can get them.
