The Figure Shows a Solenoid Having No Appreciable Resistance $5.5 \mathrm {~A} / \mathrm { s }$

Question 62

Short Answer

The figure shows a solenoid having no appreciable resistance. When the current in this solenoid is decreasing at a rate of $5.5 \mathrm {~A} / \mathrm { s }$ , the self-induced emf in the solenoid is measured to be $9.5 \mathrm {~V}$ .
((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?
