A wire of length L is bent round into (i) a square coil having N turns and (ii) a circular coil having N turns. The coil in both cases is free to turn about a vertical axis coinciding with the plane of the coil, in a uniform, horizontal magnetic field and carry the same currents. Find the ratio of the maximum value of the torque acting on the square coil to that on the circular coil. 12th Physics CBSE PYQ 2026 12th Physics CBSE PYQ 2025 CBSE 12th Physics Solution Class 12th CBSE Physics Class XII CBSE Physics CBSE 12th PYQ 2026 Physics CBSE 12th PYQ 2025 Physics CBSE 12th PYQ 2024 Physics CBSE with PYQ 2023 2025 2026 Physics 12th PYQ CBSE Solution Physics 12th CBSE sample paper solution Physics Class 12th CBSE Physics Previous year questions solution Class 12th CBSE Physics Previous year questions solution CBSE Maths 12th PYQ Solution Physics #cbseboard #cbse #cbseclass12 #maths #physics #study #boardexam #class12th #examination #education #science #physics
