The toroid is made from 3" galvanized steel stove pipe elbows covered 
with bright aluminum tape.  The toroid is 10-1/2" X 3" with a flat 
steel inner plate.  There are twelve flat "fascets" on the
outer diameter of the toroid.

I now have a 10" corn bread griddle made of soft iron and it appears 
nonmagnetized with the compass.  It has a 5 " handle from one side and 
hopefully the sparks will issue from the handle.  If there is DC, it 
should be induced to exit from the handle.  Later, I may cut the handle 
off and grind it smooth.  Also, being soft iron it should be easy to 
demagnetize between experiments.  I also plan to use a flat round steel 
pizza pan.  This experiment should be much more accurate using a flux 
gate magnetometer rather than a compass.
