Electric Charges And Fields

Question

A pair of adjacent coils has a mutual inductance of 1.5 H. If the current in one coil changes from 0 to 20 A in 0.5 s, what is the change in flux linkage with the other coil?

Solution

Given, a pair of adjacent coils.
Mutual inductance, M = 1.5 H
Current in the coil, I = 20 A
Time ,t = 0.5 s

Using formula, Φ = MI we get,
$ϕ$ = 1.5 $\times$ 20
= 30 H.
