Coil 1 has L1 = 47 mH and N1 = 104 turns. Coil 2 has L2 = 68 mH and N2 = 215 turns. The coils are fixed in place; their mutual inductance M is 5.8 mH. A 9.4 mA current in coil 1 is changing at the rate of 7.3 A/s.
(a) What magnetic flux %u03A612 links coil 1, and
(b) what self-induced emf appears in that coil?
(c) What magnetic flux %u03A621 links coil 2 (in nWb), and
(d) what mutually induced emf appears in that coil? (no picture included in problem)
