A magnetic flux of 8 x 10^-4 weber is linked with each turn of a 200-turn coil
A magnetic flux of 8 x 10-4 weber is linked with each turn of a 200-turn coil when there is an electric current of 4A in it. Calculate the self-inductance of the coil.

dϕ/dt = 8 x 10-4weber
n = 200, l = 4A, E = -nL(dl/dt)
or, -dϕ/dt = -Ldl/dt
or, L = ndϕ/dt = 200 x 8 x10-4 = 2 x 10-2H.
