Calculation #	NSTXU-CALC-131-03	Revision #	00	WP #, if any

(ENG-032)

Purpose of Calculation: (Define why the calculation is being performed.)

This is essentially a reissuance of Ref.(4) with updated explanatory text and file names to reflect the project adoption of the February 2010 Provisional design as the May 4, 2010 official design, which as of today remains the most recent design point iteration. I have recentely reviewed the calculations of Ref. (4) and confirmed that they do indeed fully apply to the present (May 4, 2010) design point. Included are the:

Mutual Inductance matrix connecting 14 circuits (12 PF, 1 OH, 1 Plasma)
(2)	Radial Force influence coefficient from 14 circuit currents to 24 "windings"
(3) Vertical Force influence coefficients from 14 circuit currents to 24 "windings"
(4) Moment (i.e., torque) influence coefficients from 14 circuit currents to 24 "windings"
