A)in the presence of any magnetic flux induction heating occurs. All
materials are constantly heated by the magnetic flux fields present thanks
to the power system. Albeit very little. You are getting some induction
heating but it is probaly insignificant

B)Well, get a BIG brass bolt from Lowes or somewhere else. I think I saw
them carrying 5/8ths bolts at my local one in the pullout drawers.
