Coil 1 has L_(1) = 25 mH and N_(1) = 100 turns. Coil 2, has L_(2) = 40 mH and N_(2) = 200 turns. The coils are fixed in place, their mutual inductance M is 9.0 mH. A 6.0 mA current in coil 1 is changing at the rate of 4.0 A/s. (a) What magnetic flux phi_(12) 12 links coil 1, and (b) what self-induced emf appears in that coil? (c) What magnetic flux phi_(21) links coil 2, and (d) what mutually induced emf appears in that coil?
