I mean, I always used to fancy as a kid why can’t we use magnets to keep a fan going in circles? Why can”t we create a perpetual machine using magnets? Even if the magnets get worn out, we can still use them for considerable time. What is the science behind it that makes it impossible?
In: Engineering
a magnet has a north and a south pole. it might push away in one direction yes, but it attracts in a different direction so the overall motion cancels out.
moving a fan also creates friction, which induces heat, which is a form of energy. you cant generate infinite energy out of nowhere because energy is conserved in our universe (as far as observed).
