A constant current I is supplied for a brief time to charge a parallel plate capacitor. The capacitor has circular plates of radius R with gap d (d << R). Point 1 is at R + d from the wire, and point 2, is at a distance R + d from the center of the capacitor.
During the time interval that the constant current I is flowing through the capacitor, the magnetic field at point 2, B2 is:
a) B2 > B1
b) B2 = B1
c) 0 < B2 < B1
d) B2 = 0
e) not enough information to tell
