10:50 PM rue_shop2: so I have a question
10:50 PM rue_shop2: lets say I have a rare earth magnet
10:50 PM rue_shop2: with a peice of steel beside it
10:50 PM rue_shop2: it'll attract the steel
10:51 PM rue_shop2: but, if I put a coil around that steel and give it a slightly opposing polarity, will it suddenly flip to pushing on the steel?
10:51 PM rue_shop2: does the field have to be comperable to that of the rare earth magnet?
10:51 PM rue_shop2: hmmm
10:53 PM rue_shop2: the problem with my hexapod overloads is that an overload is not a set current limit, but a energy-over-time mooshy thing
