i'm not sure myself but i thought perpetual motion machine meant that you put energy into it once and it would continue forever, not that it got its motive energy from an infinite or permanent source.
if you're getting your energy from magnets then what you have is a magnetic motion machine, not a perpetual motion machine.
if you're putting power into a closed system and the net result is some form of positive "work" such that you remove the power and work continues "perpetually" then you would have a PMM.
i designed a perpetual motion machine once but never got around to building it.
consisted of magnets, a surface almost frictionless, and some toggles.
[N-o-S] (_____________________[N---S]__)[S-o-N]
3 magnets, 2 on the outside and one inside a near frictionless container.
the magnet in the center would move away from the "like pole" on the right and accelerate to the other end attracted to the opposing pole. when it hit the end it would also hit a toggle that would rotate the magnets on both ends 180 degrees. maybe add some springs in the ends of the tubes to return some of the force from hitting the ends.
in any case when i presented this as a PMM to my physics prof he said it wouldn't be a real PMM because it uses magnetic force
First of all, where does it say that a perpetual motion mechine cannot use magnetic force? why not? it the thing runs forever and give off electricity, who cares what's making it go providing that it is self contained? fine, if you would like to put the definition of "magnetic motion mechine" go right ahead, the fact is that this thing runs forever and gives off energy forever, I see no reason why a PMM can't use magnetic force."i'm not sure myself but i thought perpetual motion machine meant that you put energy into it once and it would continue forever" no, that's not a nececaty.

P.S. hey, you know what, i know why ur PMM wouldn't work, it would require more energy to flip those two magnets than could possibly be produced in getting the centrel magnet to move, thin bout it, if there's a north and south pole together, the energy produced will not be nearly enough to flip one over against it's "will", plus flip the magnet on the other side, no, this PMM wouldn't work, it would take too much energy to flip the magnets.
P.P.S by the way, you may have it in a vacume, but the thing that that central magnet is sliding on provides friction, evertually, if the outer magnets did flip, the constant force of the magnet smashing into the side of the containor coupled with the drag of the central magnet on the floor of the containor would eventually smash your centrel magnets to bits. bottomline- this PMMidea has more holes in it than swiss cheese in a gun fight, sorry.
