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
Because not even does a magnet pull on metal, but thr metal also pulls on the magnet. It would be like trying to move a car by pressing against it from the inside.
Also, if you think something like rotating things, there will always be some form resistance that will gradually slow things down.
