Those who have been researching plasmoid and there interaction have up until now used the name plasma physics to describe the field and then bioactive plasma physics, low energy plasma physics or field plasma etc. to try be more specific and not get confused with high energy plasma physics. I would like to suggest the name Plasmoid physics which is close to plasma but not so close that they are easily confused.
