I can vouch for the strength of the field. Wiped out my magnetic card
stripes from about 6' away (I crossed the rope to get a closer look at
the RF power amps).
Also made the keys in my pocket tug toward the core. I quickly
crossed back to where I was supposed to be <G>. I was amazed at
how much magnetic leakage there was.

Of course. And if they ever DO find a 'proven' problem, you can bet
that the lawsuits would be flying faster that the magnetic domains flip.

Any such 'odd' behaviour by the cows may have been due to their
hearing the 'corona' noise from the lines. Most of us
wouldn't pay attention to the hiss, but the animals likely would.
