Athin coil has 17 rectangular turns of wire. when a current of 4 a runs through the coil, there is a total flux of 5 ✕ 10−3 t · m2 enclosed by one turn of the coil (note that

φ = ki,

and you can calculate the proportionality constant k). determine the inductance in henries.

Inductance, L = 0.0212 Henries

Explanation:

It is given that,

Number of turns, N = 17

Current through the coil, I = 4 A

The total flux enclosed by the one turn of the coil,

The relation between the self inductance and the magnetic flux is given by :

L = 0.0212 Henries

So, the inductance of the coil is 0.0212 Henries. Hence, this is the required solution.
