The Figure Shows a Solenoid Having No Appreciable Resistance

question 89

Short Answer

The figure shows a solenoid having no appreciable resistance. When the current in this solenoid is decreasing at a rate of 5.5 A/s, the self-induced emf in the solenoid is measured to be 9.5 V.
((a) What is the self-inductance of this solenoid?
(b) If the current is in the direction from b to a in the figure, which point, a or b, is at higher potential?
