A long solenoid of radius 2 cm has 100 turns/cmand carries a current of 5A. A coil of radius 1 cmhaving 100 turns and a total resistance of 20 Ω is placed inside the solenoid co-axially. Thecoil is connected to galvanometer. If current inthe solenoid is reversed in direction. Find thecharge flown through the galvanometer. |
