Induced EMF in the second coil, e is
2

Example 1.15 A current of 5 A flowing through a coil of 500 turns produces
a flux of 1 mWb. Another coil is placed near this coil and current in this coil

is suddenly reversed in 10 ms. As a result, the EMF induced in the second
coil is measured as 50 V. Calculate self and mutual inductance of the coils

assuming a coefficient of coupling as 60 per cent.

Solution:
