Please explain the steps for part b and d.

(14%) Problem 2: An inductor has N = 970 turns. When the current going through it is I = 0.48 A, the magnetic flux through one coil is = 2.2 x 10- T.m. The current is then changed to 1 1 = 0.86 A in At = 3.5 s. Randomized Variables N = 970 I = 0.48 A D = 2.2 x 10-6 Tom2 11 = 0.86 A At = 3.5s Otheexpertta.com 25% Part (a) Express the inductance L in terms of N, I and P. L = (N Q )/I . Correct! * 25% Part (b) Calculate the numerical value of L in H. L = 2481.4 L = 2481 X Attempts Remain 25% Part (c) Express the magnitude of the induced emf in terms of L, I, /1, and At. E = L(I1 - I)/(At) . Correct! A 25% Part (d) Calculate the numerical value of & in V
