Whenever the flux linking through a coil or a circuit changes, e.m.f. is produced

The direction of dynamically induced e.m.f. can be determined by applying Fleming's right hand-rule

Coefficient of coupling or tightly coupled coils is zero

The coefficient of self inductance is proportional to the square of the number of turns on it
