A coil has 460 turns andself-inductance 3.45 mH. The currentin the coil varies with time according to i = (680mA) cos(πt/0.0250 s).
a) What is the maximum emf induced in the coil?
b) What is the maximum average flux through each turn of the coil?
c) At t = 0.0175 s, what is the magnitude of the induced emf?
