I thought if you got a large flat donut shaped electromagnet and loaded it full of amps and voltage to where its super charged then run ionized plasma through ceramic tubes up to it and sprayed it into the hole of that magnet to where it was suspended by the field and kept building up the amount of plasma then suddenly reversed the polarity of the magnet that it would shoot a supercharged plasma ball. But then I realized that the charge wouldn't stay together through the air any suggestions on how to improve this idea.

i think first you should read up on basic electronics first.

 

then go read up on magnetohydrodynamics to realise plasma doesn't behave like that.
