Hi Richard, Paul,
                 FWIW, I should point out that one can optimise an 
aerial for picking up either E or B fields. In the first case, a flat 
plate is the obvious candidate, and in the second, a closed loop such 
as a folded dipole or "loop" aerial. There is a marked difference in 
their responses to e.s. generated discharges. Perhaps this will also 
be regarded as unconvincing. Just stating my position: I do not fall 
into the camp of a "true believer" in anything. Hopefully my position 
is that of one who weighs the evidence and forms a judgement based on 
reason until further evidence refutes whatever judgement I have 
accepted. I admit to liking Popper's ideas on the scientific method. 
Perhaps there is a definitive experiment one can perform to refute 
Maxwell's ideas? Let's hear about it.

Regards,
Malcolm
