Problem 3 Part A A copper wire with resistance 0.010 Ω is shaped into a complete circle of radius R 10 cm and placed in a long solenoid so that the axis of the solenoid and the axis of the wire loop coincide. The current in the solenoid is turned on and then slowly decreased. The magnetic field strength is initially B 0.750 T and subsequently decreases in time at the constant rate -0.035 T/s. (a) Calculate the induced emf...
A small circular loop of wire of radius 5.0 cm and resistance R = 9.0 10-4 Ω is centered inside a large circular loop of wire of radius 50 cm (see figure below). The larger loop, which initially carries a current I = 6.5 A, is cut and its current is reduced to zero over a time interval of 1.2 10-6 s. Find the average current in the smaller loop during this time interval. (The magnetic field of the larger...
