SUMMARY
The discussion centers on calculating the maximum torque on a circular coil with 50 turns, a radius of 0.2m, and a current of 5A in a magnetic field of 0.6 Web/m². The formula used for torque is τ = NBIAr cos(θ), where the angle θ is critical for determining torque. The maximum torque occurs when θ is 90 degrees, not 0 degrees, as initially assumed. The standard unit for torque is Newton-meter, which is equivalent to Web-A.
