A magnetic flux of 8 × 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.

Given:


Magnetic flux(Φ) = 8 × 10–4 Wb


Number of turns(n) = 200


Current(i) = 4 A ω


Formula used:


, where L = self inductance, n = number of turns, Φ = flux, i = current


Putting the values, we get
