I haven't had the time to participate in this, but in a brief look, it
looks pretty silly. Of course EZNEC shows no current difference across a load. The EZNEC model of a load has zero length, so the current at both terminals has to be the same. You will see a current change over the length of a model of a conductor, because it does have length. The coil in the web site pictures certainly has length, so why should you be surprised to find a current change over its length? Did the experimenter perhaps do the same test with the meters placed the same distance apart with just a conductor in between? Would there be some great revelation in finding that the current was different at the two points? I was intrigued by the claim that a toroid measured significantly different from one end to the other. I wonder if the tester tried reversing the meters to verify that he got the same reading in both cases. If he did, I'd be interested in learning more details. Unfortunately, the main objective of the web site seems to be to insult Tom, W8JI, rather than to be objective. So in my mind that leaves the possibility open that the experimenter is more interested in finding evidence that would disprove Tom than in presenting carefully measured and objective data.

I added picture of current distribution when using inductance in the form of loading stub as described earlier and from Eznec file supplied by Cecil. It is at the end of the article at http://www.k3bu.us/loadingcoils.htm It shows the jump accross the stub, but when replaced by lumped inductor, the Eznec shows constant current accross the coil.
