Only in the far field does inverse square hold. The boundary between near
and far fields is where the radiated energy = the stored (in the field)
energy.  There's a lot of stored energy in the field around a TC, and
they're not particularly good radiators.  It's probably many coil heights
away before you're in the far field.
