Based on this notion, it occurred to me that a horizontal compass placed centrally above one pole of a vertical bar magnet might rotate. I tried it a few months back, but saw no sign of rotation. Mind you, it was very difficult to get the compass to stay balanced. Perhaps another Vort will have more luck. :) [snip] Regards, Robin van Spaandonk http://users.bigpond.net.au/rvanspaa/ Competition provides the motivation, Cooperation provides the means.
