19-6 The Magnetic Torque on a Current Loop
... Figure 19.21 (overhead view). The distance from each force to this axis is W / 2, each force has a magnitude of F = IHB (from equation 19.7), and the angle between the line we’re measuring the distance along and the line of the force is 90°. A factor of 2 accounts for the two identical torques, whic ...
