Seem I am the lucky one, now it is dark I pulled all my little magnets off to see if the flickers at all, nope nada. I barely get .5v AC on my digital multimeter and with my little magnets on I get about 1.1v AC.
I did some searching for something in Austin for "re-charging / re-magnetizing magnets and came up with no hits. I did email kjmagnetics.com - they have a YouTube about doing this and they have ALL kinds of magnets. Some of their neodymium magnets have such a powerful pull you can't pull them apart if you put two of them together!
Thank you for those tips on how to get the horseshoe off.
