A circular coil with N1=5000 turns is made of a conducting material with resistance 0.0100 Ω/m and radius a=40.0cm. The coil is attached to a C=10.00μF capacitor as shown in (Figure 1). A second coil with radius b=4.00cm, made of the same wire, with N2=100 turns, is concentric with the first coil and parallel to it. The capacitor has a charge of +100 μC on its upper plate, and the switch S is open. At time t=0 the switch is closed.
A What is the magnitude of the current in the larger coil immediately after the switch is closed?
B What is the magnetic flux through each turn of the smaller coil immediately after the switch is closed? (Since b< C What is the direction of the current in the smaller coil immediately after the switch is closed?
D What is the direction of the current in the smaller coil at t = 1.26 ms ?
E What is the magnitude of the current in the smaller coil at t = 1.26 ms ?
