why electromagnets aren’t used in piston motors, including internal combustion or not including internal combustion

Question

Will pistons specifically in the cylinder ever use electromagnets to propel the piston and to spin the driveshaft like gasoline motors?

Answer 1

I’m sure someone could correct me if I’m wrong but it’s an “Occam’s Razor” as pistons would lose energy themselves by virtue of more moving parts opposed to just cycling the driveshaft itself. It’s like adding a loop to a straight road, may look cool but the fastest soloution most optimal would be a straight line.

If you can use electromagnets to fire the piston, you can just put that energy to the driveshaft and skip the magnets alltogether. Can it exist, sure. Is it efficient on a mass scale, not at all.
