These simple relationships hold true only when there is no mutual coupling of magnetic fields between individual inductors.
The formula is easily extended to any number of series coils with mutual coupling.
These new techniques are also able to deal with mutual couplings.
There are two basic approaches available for dealing with mutual couplings and active components.
He used these to analyse circuits containing mutual couplings and active networks.
The second approach is to extend the classical method so that it includes mutual couplings and active components.
However, this can result in significant mutual coupling between elements, which means that each antenna's phase measurement will be corrupted by the other's.
The influence of the mutual coupling between wind and current can immediately be seen if one considers an infinitely large electric conductivity σ.
Furthermore, control of the radio frequency or microwave radiation pattern is efficiently increased, and mutual coupling between antennas is also reduced.
These secondary flux paths produce mutual coupling between the phase windings of the single-stack stepping motor.
