Guest guest Posted May 18, 2001 Report Share Posted May 18, 2001 Hi, I have a friend who has built a " Mr. Thumpy " from a Radio Shack strobe light kit. He was asking me about how to tell north and south on the magnetic coil. I've never built one myself and wasn't sure whether he needed to pay any attention to the north and south on that type of device, and have no idea of how to find out in any event. Anyone have any ideas on this? Dennis Quote Link to comment Share on other sites More sharing options...
Guest guest Posted June 13, 2001 Report Share Posted June 13, 2001 Hi Dennis I use a compass on my Beck magnetic pulser. Hold the compass near to one side of the coil, fire, if the needle is attracted to the coil, then that is the north pole, if repelled than that is the south pole. The North pole is preferred to use.

Guest guest Posted June 14, 2001 Report Share Posted June 14, 2001 Thanks Dave, I would never have thought about using a compass. It makes sense and is so simple. I guess I'm too use to looking for the " difficult " answers. The easy ones simply fly right by me. Dennis Re: Info on Mr. Thumpy Hi Dennis I use a compass on my Beck magnetic pulser.
