Abstract

LAST week, while working with a small Voss machine, I accidentally observed, on stopping the machine, giving about two turns in the wrong direction and then re-starting the machine in the original direction, that the poles had reversed. I repeated the experiment a dozen times, and invariably the reversal occurred. The reversal was observed by examining the spark between the knobs.
