4) Induction Effect. A very long solenoid of radius R-2.5 cm has n 5 turns/cm. Starting from an initial current of io 50 A at 1 = 0, a steadily increasing current is driven through the coils of the solenoid, at a rate of didt = 10 A/s. The solenoid is surrounded by a square flat "pickup" coil of N= 100 turns and of side lengthに10 cm (oriented with its plane perpendicular to, and its center at, the solenoid axis)....
