(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.

When experimenting with the simulation, you can manipulate the size of the motor, the strength of the input current, the strength of the magnetic field, and the number of turns in the wire:
