In the figure, the current in a solenoid having no appreciable resistance is flowing from b to a and is decreasing at a rate of 9.6 A/s. The self-induced emf in the solenoid is found to be 8.4 V.
(a) What is the self-inductance of the solenoid?
(b) Which point, a or b is at higher potential?
What will be an ideal response?
Question 2
Suppose that you wish to construct a simple ac generator having an output of 12 V maximum when rotated at 60 Hz. A uniform magnetic field of 0.050 T is available. If the area of the rotating coil is 100 cm2, how many turns do you need?
A) 8
B) 16
C) 32
D) 64
E) 128
