in this question to find emf i have used formula
e=-
=b.ds
and to find direction of current i have used lenz law according to which indused emf oppose its own cause

Question 1: (10 points) X X X х A circular RC Circuit of radius 4=35.0cm with a 140 (ohms) resistor in series with a 4.7mF capacitor is placed in a region with magnetic field B=0.42T into the page, as shown. At t=0, the magnetic field begins to increase at a constant rate dB/dt=0.020T/s a) What is the magnitude of the constant emf induced in the circuit by this charging magnetic field? b) At t=0, the capacitor is uncharged. It begins...
5) A solenoid with 2 x 106 turns per meter runs through the x-y plane. It initially has a current of 7 amps running clockwise. A wire shaped like a equilateral triangle would 10 times with sides of length 2 meters is placed in the x-y plane in the solenoid. Over a a time of 0.7 seconds, the solenoid changes its current somehow which induces a (average) current in the triangle of 16 amps running counter-clockwise. If the resistance of...

3. Electromagnetic Inductance. Consider a single loop under magnetic field. (a) If the area A = 0.012[m) is constant, but the magnetic field is increasing at the rate of 0.020 T/s), determine the induced emf. (Use Faraday's law; the induced emf in a loop equals the absolute value of the time rate of change of the magnetic flux through the loop.) (b) If the total resistance of the circuit is 5.0(82), find the induced current. (c) Suppose we change the...
