1. depends on what type you are referring to.
   Axial driven, like a standard electrical motor that is on an axis or rotation….or something more exotic.

   Something with friction based operation or something that is frictionless in operation.

   You don’t need a vacuum to operate a proper magnetic motor. just plain old air.

   How far are you willing to go? Work and cost…shouldn’t matter….

2. Electric motors are driven by electromagnetic force. So yeah, they are basically just rotating magnetic fields that turn the rotor around. They are powered by electromagnets, which are, of course powered by electricity, usually supplied by a wall outlet or a battery.

   If you hear of people that claim to have an engine that runs purely off of permanent magnet power and they use terms like “zero point energy” and “over unity” to describe how the permanent magnet fields drive the engine perpetually while powering a generator or something, then turn the other way and do not give any financial information, because they are all a scam. Those things break a bunch of laws of physics. But you certainly can see a whole bunch of them on youtube that appear to work. People have been claiming that for as long as they have known about magnets and energy, but none have ever been produced, except by heresay and grainy videos. You wonder why you can’t ever see them in person unless you give a bunch of money to some sketchy person in a foreign country who promises to let you in on the big magnetic energy breakthrough? Because they don’t exist. Period.

3. You need to define exactly what you mean by a “magnetic engine.” Engines transform power from one form (often chemical, as in a fuel) to another (often mechanical). What do you anticipate as an energy source, and what form do you want as an output? What physical or chemical processes will you use to accomplish the transformation?
