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

In order for electromagnet to function on such high temperature environment you need very high energy. That means that you net energy outcome from the system goes down since you need energy to overcome not only engine’s inertia but also to power the electromagnet now. Also what kind of function do you want the electromagnet to have?
