Hi, Yes about 23 to 25 kilowatts to make somewhere between 150 to 200lbs thrust, and yes the air entering the magnetic field would get ionized and would push with the rest of the ions. Unlike the ion / plasma engines made to work in space, this ion engine would use just electricity (lots of it) to firstly ionize some of the air at the front of the engine, and then to accelerated the ions with a magnetic field, this will make the ions (which are the same density as the other air molecules that didn’t get ionized at the air intake) move through the rest of the air and push them out the back as well, and then finally neutralised the ions with electrons from emitters at the back of the engine.
