Being a bit lazy ;) the freq of coil B according to
TESLAC 2.06 is 276 Khz, coil A won't calculate
due to the 6-1 aspect ratio which TESLAC doesn't
like. I reality, the frequency shifts all over the place
depending on where the coil is located, etc. So in
short, any answer between 250-350 Khz is close
enough for government work. <G>
