Fantastic news! We've Found the answer you've been seeking!

Magnetic flux of 0.5Wb is produced in a coil of 900 turns on a wooden ring by a current of 3A. Calculate:
(1) The inductance of the coil.
(2) The average e.m.f. induced in the coil when a current of 3A is switched off, assuming the current to fall to zero in 10 milliseconds.
(3) If a second coil of 600 turns was uniformly wound over the first coil with magnetic flux of 0.4Wb. What will be the mutual inductance between the coils.
