Hi, I'm currently doing an research experiment into the behaviour of plasma around magnetic fields. I will be using an arc welding machine for the plasma and an electromagnet. (So I can adjust the field's intensity as an independant variable.) The arc should bend in the presence of a magnetic field, and the how much it bends is dependant on the strength of the field. What I need to do is to be able to calculate/predict how much the plasma will bend if I know; *The momentum of the plasma, *The magnitude of the magnetic field, *The kinetic energy of the plasma, *The heat energy caused when the plasma strikes a surface. Firstly, is there any way I can calculate the momentum and the kinetic energy if I know the heat energy given off when the plasma strikes a surface? If not, is there any other way I could find the plasma's p and KE? And, furthermore, (and more importantly,) is there any way, to calculate how much the arc bends once I know the momentum, kinetic energy and magnetic field magnitude? If not, what should I be measuring to calculate how much the arc bends? I can deal with rather complex maths, but, as I'm only a highschool freshman and haven't learned too much calculus, the simpler the better. Regards; -Alice. PS: Sorry if this doesn't make a lick of sense, I may have gotten a bit mixed-up somewhere along the line. I'm relatively new to physics, you see. EDITED: To spare you all some tedious background info on yours truly.
