Question

The mutual inductance of two coils (1 and 2) is 48.0 mH.
Find the magnitude of the emf induced in coil 2 if the current in coil 1
is 26.0 A and decreasing at 3.00 A/s

Expert Solution

Step 1

Given data

$L = 48 mH \frac{d I}{d t} = - 3 A / \sec$

Step 2

For steady state current

$\frac{d I}{d t} = 0$

Therefore, emf for the coil is

$\begin{array}{rcl} e & = & M \frac{d I}{d t} \\ = & 0 \end{array}$
