MHT CET 2025 Physics question
Two coils P and Q are kept near each other. When no current flows through coil P and current increases in coil Q at the rate , the emf in coil P is 12 mV. When coil Q carries no current and current of 1.5 A flows through coil P, the magnetic flux linked with the coil Q in mWb is
Answer: (D)
Solution
The emf induced in P is , so H mH. By reciprocity the mutual inductance is the same in both directions, so the flux linked with Q when P
