Hojo Motor first of all i have heard about many magnetic electrical motors i am slightly skeptical. I have an idea about making one could there be two magnets in a vacuum sealed container. Each one repelling and attracting in turn pulling a charged object back and forth creating mechanical energy then converted into electrical energy. First of all i am a bit of a layman and i am only interested i do not know much about physics as i would like too, as you can tell . Secondly, i do not know how this charged object could turn its constant movement into efficient mechanical energy. i was thinking that it could compress air? some how. Then the compressed air could be turned from Mechanical into electrical energy though an induction motor or generator.
Again thanks for the advice and help and sorry for the strange wording of the question .
no silly answers
Chosen Answer:
A solenoid can move alternately, as in a doorbell. You can also use a Stirling engine to produce reciprocation, which is being studied now in several places, with the motion driving a linear alternator.
Note that the moving object does not have to be charged. A piece of soft iron works well.
The output of a linear alternator is alternating current, so you don’t need to compress air. I’m working on such a device.

There are LIMs or Linear Induction Motors. But what you refer to is nowhere near that. Your proposed device wouldn’t really work well. Charged particles would require massive amounts of applied energy, and would produce very little energy. You would have a high net loss in energy.
