SUMMARY
The discussion focuses on calculating the torque acting on a rectangular coil of wire, consisting of 15 turns, measuring 10 cm by 5 cm, carrying a current of 0.90 A, and positioned at a 30° angle in a uniform magnetic field of 0.50 T. The torque is determined using the formula τ = μ × B, where μ = NiA. The calculated torque is 0.16875 Nm, but there is a need to reassess the angle due to the direction of the magnetic moment vector μ.
