"Large" or "small" are not quantities.

For electrically small loops, reactive fields are dominant for:

r 0.16*lambda
given that I have already demonstrated that, and more, what importance
do you attach to this that hasn't already been shown?

Smaller loop size does not result in smaller reactive field zone.

What a curious defense for magnetic antennas's noise immunity.

However, the magnetic antenna is not immune from the reactive fields
of noise emitters that are very much larger than any loop discussed
here. It is the field of the emitter that is important. I thought I
would wait and see if anyone cottoned on to that aspect of the
discussion. If we proceed with the assumption (repeated here):
Smaller loop size does not result in smaller reactive field zone.
then the magnetic antenna is doomed to noise in the same sense as an
electric antenna is. Offhand I would speculate that in an apartment
situation, a magnetic antenna on the balcony is saturated with
reactive noise fields.
