I get that the main reason perpetual motion isn’t possible is because energy loss due to friction, but that’s not the case with magnets (I think?). Why can’t perpetual motion be achieved with magnets? What can’t we make something that spins and creates energy using magnets to propel a turbine?
In: Physics
If you use a magnet to pull one side forward to spin the turbine, at some point it will also pull after the magnet is moving away. At each rotation there would be a slight reduction in speed until it stops due to magnets and friction.
