Some dude in California has a nice Almost-Zero friction drive that works on magents. think he developed it in the 1980s...BUT perpetual motion is not attainable.... by the way.
The equations we use that govern all motion basically state that we cannot go beyond 100% eficiency in any mechanical cycle, which translates into - perpetual motion, haha!
BUT when looking at grey areas where current physics is not clear on - like Superconducters which defy some of the laws of magantism - then there is ALWAYS the possibility that we just don't know of the solution yet. Just like cave men didn't know about electricity.
So until that day - Perpetual motion = Myth.

No because if you were to build something mimicing perpetual motion with magnets there would still be the initial force imparted to whatever you built, and then you would have to account for the magnetic force from the magnets. In other words, it may look like it's free, but the energy is coming from somewhere.

The stress on the ball through your 1/2 sphere of magnets will be equivalent contained in the x instructions hence off putting one yet another. the ball will nonetheless journey wind resistance and friction with the air molecules, merely because you're in a magnet does not advise the air is lengthy previous.

Perpetual motion is only a theory.

Magnets eventually break down.
