The figure below shows the end-on view of a long solenoid that contains a coil positioned such that both are coaxial. The solenoid has a radius R = 10.0 cm and a turn density n= 650 turns/m. The single-turn coil has a radius r = 4.00 cm. The current through the solenoid is in the direction shown and is given by i= i(1-e "), where i = 30.0 A and a =1.60 s1. -at (a) Find the induced emf in the coil at t = 0.200 s and (b) the direction of the induced current in the loop. Justify your answer. solenoid R coil
