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 $830 A / s$ . Suppose that the current described is in the second coil rather than the first. What is the induced emf in the first coil?

Solution

$E M F, | e_{1} | = M (\frac{d i_{2}}{d t}) = (3.24 \times 10^{- 4}) (830)$
$= 0.27 V$
