The governing equations of a linear two-terminal inductance are:
(1.4-1)
where is the flux-linkage at tin Weber-turns, v(t) is the voltage across the inductance
and i(t) is the current entering the higher potential terminal. i(0) is the current in the inductor
at t 0.
A coil can have induced electric field and induced e.m.f. present in it due to accel-
erated motion of charges (i.e., time-varying current) in the circuit in which it is connected
and/or due to accelerated motion of charges taking place in another physically separated
circuit. The e.m.f. induced in the coil due to its own time-varying current ...
