A coil has 395 turns and self-inductance 3.25 mH. The current in the coil varies with time according to i = (680 mA) cos(?t/0.0250 s).
(a) What is the maximum emf induced in the coil?
V
(b) What is the maximum average flux through each turn of the coil?
Wb
(c) At t = 0.0190 s, what is the magnitude of the induced emf?
V
