answered-by-expert Expert Answer

Current, i = (Cθ / n H A )

Here, n = no. of turns in the coil.

A = Area of coil.

H = Magnetic field due to magnet.

C = Restoring couple per unit angular twist.

θ = Deflection of coil in equilibrium position.

After performing the expt. and knowing the value of above parameters, the given formula can be calculated to find the current.
