50 cm 10 cm 8.0 A R = 1.0 x 10-3 2 A small circular loop of wire of radius 5 cm and resistance 1E-3 Q is centered inside a large circular loop of wire of radius 50 cm. The larger loop, which initially carries a current of 8 A, is cut and its current is reduced to zero over a time interval of 1E-6 s. Our goal will be to find the average current in the smaller loop during this time interval. (The magnetic field of the larger loop is approximately constant over the smaller loop.)

PART (1) Assume capacitor is fully charged when switch is at position 'a' for about 10 minutes. The switch is changed to position 'b' at t= 0. What is the current in the circuit immediately after the switch is closed? Assume after some time, the current in the circuit is 80.0 mA when the switch is at position 'b'. Can you find, what will be that time? 9.0 V 부 Paragraph a itur b 1.0 με PART (II) Assume a magnetic field of 5.2 T present inside the cyclotron. An electron enters the cyclotron with speed of 2.0 x 107 m/s. What is the radius of the electron's orbit just before they exit from the cyclotron. BI U A/ 10 Ω E✓ E GO + v

Taking R = 1.20 kΩ and ℰ = 470 V in the figure shown below, determine the magnitude and direction of the current in the horizontal wire between a and e. magnitude ?mA
