Interesting, I've noticed something really similar with our track, except it's demagnetized unevenly so there are magnetic hills and valleys messing up our consistency. Then again we've been using it a lot for a year now and it's time for a new one. Does anyone have any tips for ceramic magnet maintenance though? I suppose not leaving magnets near the track for prolonged periods of time helps.My teammate and I have build two tracks out of ceramic magnets in the last year. The demagnetization was definitely noticeable over time - when we build the first track about 13 months ago, it comfortably levitated 2000g, and it now only supports about 1200g. We're planning to build a third track next month using stronger ceramic magnets such that we won't have any significant demagnetization problems before states.nah, i was not referring to you actually, was more of a general question, i have a surplus of over 200 1-7/8 inch by 7/8 inch by 1/2 inch ceramic magnets each with a 3 pound lift force and i thought i might be able to make a track for my schools other team and i am absolutely stumped as to how i do this. the only way that makes any sense is to anti-align them and as far as i know that would demagnetize them very quickly. i've seen other teams use ceramic magnets so i was wondering how people do it. Do people really anti-align them like that and does the demagnetization actually happen or is it not noticeable?
