Question

The magnitude of the self-induced electromotive force in solenoid is 0.02 V when the current is increasing at a rate of 0.054 A/s

(a) Find the inductance of the solenoid

(b) If the solenoid has 350 turns, what is the magnetic flux through each turn when the current is 0.63 A?

Answer 1

$B=\frac FA=1.4~mT,$

$\Phi=BS=2.6~Wb.$
