Question

Two coils have mutual inductance $M=3.25\times {10}^{-4}H$. The current $i_1$ in the first coil increases at a uniform rate of $830A/s$. What is the magnitude of the induced emf in the second coil? Is it constant?

Answer 1

$\left|e_2\right|=M\left(\frac{d{i}_1}{dt}\right)=(3.24\times {10}^{-4})\left(830\right)$
$=0.27V$

Yes, the magnitude of induced emf in the second coil will remain constant as the rate of current is constant.
