This conversation is closed.  Magnetic/kinetic energy
production.  So lets say you have a magnetic ring, that is held
in a vacuum that is sealed so it's safe from outside forces. And
there are other magnets inside the object that makes the ring
spin. You have it to where the only friction comes from the ring
hitting something, to produce energy through the movement of it
makes heat, or it uses the kinetic energy for powering
something, would that work, or would this just be a whole waste
of time?  I'm still in high school, and I haven't done physics
so there may be forces I'm overlooking that will be obvious to
someone who has studied it.    • thumb      Lejan .      • +1
Jan 23 2014: Assuming your experiment was successfully set up as
you describe, how would the 'other magnets' make the magnetic
ring spin?      As I assume all magnets would be permanent
magnets (no electro-magnets), the whole system of magnetic
forces would get itself within a force equilibrium, by which no
ongoing spinning could sustain
