MHT CET 2024 Physics question
A closely wound coil of 100 turns and of cross-section has a coefficient of self inductance 1 mH. The magnetic induction at the centre of the core of a coil when a current of 2 A flows in it, will be
Answer: (B)
Solution
Total flux linkage , so the flux through each turn is Wb. The cross-sectional area is , so the magnetic induction at the
