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
Magnets for all we care during our lifetimes are “perpetual”. The problem is that you eventually need moving parts that cannot levitate and will eventually wear out due to friction
