The diagonal coefficients " L m, m " are called coefficients of self-inductance, the off-diagonal elements are called coefficients of mutual inductance.
22.
The inductance of a coil is dominated by the mutual inductance between the turns of the coil which increases its inductance according to the square of the number of turns.
23.
Transformer self-inductances L _ P & L _ S and mutual inductance M are, in additive and subtractive series connection of the two windings, given by,
24.
The Campbell bridge circuit can also be used to determine transformer self-inductances and mutual inductance using a variable standard mutual inductor pair for one of the bridge sides.
25.
The mutual inductance between the two windings results in an induced voltage on the secondary side, whose magnitude is determined by the ratio of turns between the two windings.
26.
Two ( or more ) inductors in proximity that have coupled magnetic flux ( mutual inductance ) form a transformer, which is a fundamental component of every electric utility power grid.
27.
Designers tend to avoid the complication of mutual inductances and transformers where possible, although transformer-coupled double-tuned amplifiers are a common way of widening bandwidth without sacrificing selectivity.
28.
For instance, channels can be cut between cavity resonators, mutual inductance can be used with discrete component filters, and feedback paths can be used with active analogue or digital filters.
29.
Many types of parasitic oscillation are caused by small interelectrode capacitances ( parasitic capacitance ) or mutual inductance between adjacent wires or electronic components on the circuit board, which create an inadvertent feedback path.
30.
Bosworth later extended the experiments to study the thermal mutual inductance; however, he did not report on the thermal inductance in a heat-transfer system with the exception of a fluid flow.
