Question

a moving coil galvanometer has 100 turns and each turn has an area of 2 cm^2. The magnetic field produced by the magnet is 0.01 T. The deflection in the galvanometer coil is 0.05 rad when a current of 10 mA is passed through it. Find the torsional constant of the spiral spring.

Answer 1

A moving coil galvanometer has 100 turns.

Answer 2

Answer:

A moving coil galvanometer has 50 turns and each turn has an area 2 × 10-4m2. The magnetic field porduced by the magnet inside the galvanometer is 0.02T. ...
