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

Are you saying to use the magnet to drive the piston? Not like an electro magnet as a ignition coil or solonid or valve control? Many engines have electro magnets in them, but for things like fuel pumps etc. I think some also may use them for variable valve timing.
If you want the magnet to drive the actual piston, it’s just way less efficient than just having the electromagnet in a true electric motor. The while point of the piston is to compress gas/air so you can blow it up. A electric motor is much more efficient in turning a shaft directly instead of driving a piston.
