The circuit sketched below contains a switch, an ideal battery
with an emf of 13.5 volts, a 19 MΩΩ resistor, and an air-filled
capacitor. The capacitor has parallel circular plates of radius 5.2
cm separated by 1 mm. At time t=0 the switch is closed to begin
charging the capacitor. You may assume that the electric field
between the plates is uniform.

1. A 85 turn elastic circular coil of wire initially has a radius of 74.2 cm and is immersed in a uniform magnetic field with a strength of 0.495 T. At t 0, the coil is released and begins decreasing in radius at a constant rate of 7.22 cm/s. While it contracts, the number of turns does not change. a) Write the magnetic flux through a single turn of the coil as a function of time. (Hint: What causes the...
