Has any one invented a material/ substance that does not allow the field of a magnet through it
Google: Magnetic Shielding
Superconductors also have that property. Specifically, Type 1 superconductors expel flux perfectly up to a critical field where they can no longer keep the field out. This is called the Meissner effect.
You can read up more on Diamagnetism. A superconductor is a perfect diamagnet, where it keeps magnetic fields from its interior. But a superconductor cannot keep a magnetic field out for all intensities. Once the critical field is met, it looses its perfect Diamagnetism and can no longer oppose magnetic fields.
thanks for your replies, very helpfull in my quest for a perpetual motion machine using magnetism and gravity
They're only helpful if they've convinced you to abandon the quest!
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.
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.
