Note that the perpendicular to the loop makes an angle θ with the field that is the same as the angle between w/2 and F. (b) The maximum torque occurs when θ is a right angle...Note that the perpendicular to the loop makes an angle θ with the field that is the same as the angle between w/2 and F. (b) The maximum torque occurs when θ is a right angle and sinθ=1. (c) Zero (minimum) torque occurs when θ is zero and sinθ=0. (d) The torque reverses once the loop rotates past θ=0.
