I would have to say that in my experience AMS are not the most "customer friendly". I purchased a part from them and wondered why it had not arrived. I later logged back in and found out my order had been cancelled soon after I had placed it. It took them 3 weeks to get around to sending me an email to say the order had been cancelled. Yet to this day they still have the same part listed as "available" on their website.

Max, I was having trouble understanding the whole polarity thing, but your photos really help to explain the difference between those external and internal coils. Thanks for posting the information. I recently added some extra rare earth magnets in behind an old Pope flywheel which boosted it back to normal. Took me a while to work out the whole N/S thing, and to get the magnets so they were all facing the right direction and not repelling. I must have it right as I used a compass and the needle rotates N to S as I pass it across the face of the magnets, just as I would expect.
