MHT CET 2023 Physics question
A long solenoid has 1500 turns. When a current of 3.5 A flows through it, the magnetic flux linked with each turn off solenoid is weber. The self-inductance of solenoid is
Answer: (A)
Solution
Self-inductance is defined by , so where is the flux through each turn. H, option (a). Trap:
