A coil with 209 turns has a magnetic flux of 45.1 nT-m² through each turn when the current is 2.44 mA. (a) What is the inductance of the coil? What are the (b) inductance and (c) flux through each turn when the current is increased to 5.92 mA? (d) What is the maximum emf & across the coil when the current through it is given by i = (4.18 mA) cos(wt), where w=272 rad/s?
