This current loop antenna discussion has been replayed continuously since
the 1920's in both professional and amateur circles, usually with more smoke
than light.
If you want to know how a loop works get a copy of:
R.E. Burgess, The Screen Loop Aerial, Wireless world, October 1939, Vol. 16,
page 492
There are also other discussions and references in Terman, Jasik, etc.
A small loop is just a Faraday's law device. If you understand Faraday (V=n
(dphi/dt)) and a dash of Ampere's law, the discussion converges quickly.
