Some questions about these magnets:
I'd like to know roughly how much weight two of those could lift or what force is needed to separate two of these... According to bricklink, the magnet was produced from 1980-2009, would there be a considerable loss of strength between magnets produced in the early days and later? I suppose how they were stored or how much they were played or dropped would also influence heavily their remaining strength... I suppose I could re-magnetize them with a neodymium magnet, anyone care to guess or experiment about how strong such rejuvenated LEGO magnet would be?
