Question

The magnitude of the self-induced electromotive force in solenoid is 0.03 V when the current is increasing at a rate of 0.064 A/s.

 

           a.) Find the inductance of the solenoid.

 

           b.) If the solenoid has 450 turns . What is the magnetic flux through each turn when the current is 0.73 A.

Answer 1

$\Phi=\frac{\mu_0 NAI}l=6.5~V\cdot m.$
