1. The problem statement, all variables and given/known data A current loops is oriented in three different positions relative to a uniform magnetic field. In position 1, the plane of the loop is perpendicular to the field lines. In position 2 and 3, the plane of the loop is parallel to the field as shown. The torque on the loop is maximum in: 2. Relevant equations Τ = NiABsinΦ 3. The attempt at a solution Th equation states sin(pi/2) is when torque will be maximum, but the answer states that figures 2 and 3 are when the torque on the loop is maximum. If the plane of the loop is parallel to the field, wouldn't that mean torque will be 0? I need clarification on why figures 2 and 3 are the answer, and not figure 1.
