Question

Detailed for five stars.

A rectangular metal loop with Rwire resistance is placed next to one wire of the RC circuit shown. The capacitor is charged to V volts with the polarity shown, then the switch is closed at t = 0 s. What is the direction of current in the loop for t > 0s? What is the induced current in the loop at time t? Assume only the circuit wire next to the loop is close enough to produce a significant magnetic field. (Sketch, reasoning and assessments are required for full credit).

Explanation / Answer

a. counter clock wise

let B is the magnetic field and

b. indiuced emf e =NAB =

here Area A = (Lh)

so induced emf e = LhB

induced curretn i = LhB/R

where R = resistance
