In addition to the advice mjmiddle provided, I suggest you insert a Revolute Joint, Body-Ground. Let the ground Reference coordinates be the center of the coils and orient the Coordinate System so that the Z axis is along the coil axis. Let the Mobile location be the 3 faces on the short arm at one end of the coils. Apply a Joint Load to rotate the Mobile end by a specific angle.  Use a Joint Probe to measure the Torque being created to rotate that short end.
