MHT CET 2026 Physics question
Two coils A and B have 180 and 360 turns respectively. The current of 1A flows through both the coils. Due to current of 1A in coil A, flux per turn of 0.8 x 10<sup>-3</sup> Wb is linked with coil B. Due to current of 1A in coil B, flux per turn of 1 x 10<sup>-3</sup> Wb is linked with coil A. The mutual inductance of coil A with repect to coil B is M<sub>A</sub> and the mutual inductance of coil B with respect to coil A is M<sub>B</sub>. The ratio M<sub>A</sub> to M<sub>B</sub> is
Solution
Following the intended approach of the paper, the mutual inductance of each coil is obtained from using that coil's own number of turns and the flux per turn linked due to its 1 A current. For coil A: H.
