The number of turns in a coil is 250. When a current of 3 A flows in this coil, the
flux produced is 0.3 mwb. When the current is reduced to zero in 3 milli seconds,
the voltage induced in a coil is 60 volts. If the coefficient of coupling between the
coils is 0.8, find the self-inductance of the two coils, mutual inductance and
number of turns in the second coil.
