hi guys, i was searching about the magnetic induction of Faraday and i was thinking of making a permanent spining CD with magnets, like something like this:
Explanation:
what i wanted is like to make a super simple design that if i put that magnet it will start repeling the others so the CD with magnets will spin forever without stoping :D.
I love cows and monkeys including cookies :D

Also won't the magnet demagnetize each other if you keep them in each others presence?

If you put this device in a frictionless vacuum, the sum of forces applied to the disc will be 0. Look at your diagram: the magnet at 3 o'clock is doing nothing, the magnet at 1 o'clock is pushing CCW at a force of F(N), and the magnet at 5 o'clock is pulling CW at a force of F(N), etc etc etc with all magnets.
Basically the magnets do nothing. Maybe add mass to the disc, but nothing more.

I'm not sure that that's provable. On the other hand perpetual motion violates lots of different laws of physics.
Your machine wouldn't produce motion. It could store it rather inefficiently, but where's the point in that?
It would be instructive to look at your setup and one that is the same except with the magnets removed. The balance of forces will be the same (as Edan said, zero).
And, of course, if you used it to induct a current it would slow down. It's odd but you can view it as a kind of friction: the electrons individually can be pushed around but when there's lots it can be a surprising force. If you have a hand generator you can feel the difference by hooking up lights of different wattages.
I like how I've said the same thing over and over in this thread in marginally different ways.
I give a little into the moment like I'm standing at the edge (I know)

Just one more step, I could let go

Physicists knew that all along. Mythbusters showed it on TV, explaining it like you would to an eight-year-old.

nectar: Is there any particular reason why the arrows in your diagram go counter-clockwise?
Couldn't they just as well go clockwise?

You're judging this shit the wrong way. People don't like other people whose abilities they think less of.

I think aaronjer is defined as anyone other than himself.
So anyone who isn't aaronjer is in fact aaronjer.

Isn't this a paradox?

No, it's not a paradox, it's just wrong. We've been over this!
But seriously. Trying to get Kelli to attack an enemy city with more than one unit at a time? Impossible. At least it's impossible without a complex system of puppetry to control every movement from afar.
And you'd better show up at Outback tonight! With your car that you may or may not be old enough to drive. I can't remember how old you are.
