Why then does the 28 guage enamel wire that makes up the coil withstand
those amperage levels? Does the ground need to be of a fairly low guage
because
it doesn't form a part of the lump inductance of the coil, because of high
current,
or for some other reason? I would appreciate if you'd clarify this.
