+1 862 207 3288 A coil with 150 turns has a magnetic flux of 50.0 nT · m2 through each turn when the current is 2.00 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 4.00 mA? (d) What is the maximum emf Eacross the coil when the current through it is given by i = (3.00 mA) cos(377t), with t in seconds?
