Has any one invented a material/ substance that does not allow the field of a magnet through it
Perpetual motion is simply not allowed by thermodynamics. Please save yourself the time of a wild goose chase. If you insist on continuing, at least spare the poor readers of PF forum from yet another fruitless thread.Reading another post about gravity being a type of energy, from which i derived it isn't. Therefore a PM machine using only gravity and magnetism does not break the law of energy conservation. Im sure there's more to it than that, if any could enlighten me i would be gratefull.
