OK guys, this is fun and interesting, but, how you are going to get these
cows and power lines into the student laboratories, which, of course would
be interesting. Bill

I would think minimum would be perpendicular to the power lines, but
now that I think about it, I am not sure. I do believe it would be a
small effect regardless, since although high voltages are involved,
the towers are tall, and net voltage over all 3 wires is always zero.
