Sep 02, 2015 · Inductance or self inductance is the property of a current carrying conductor where an EMF is induced in it when there is a change in flow of current. When an alternating varying current flows through the inductor coil, the magnetic flux in the coil will also vary, to produce the induced emf. Definition: coefficient of self inductance. The ratio of the back EMF to the rate of change of current is the coefficient of self inductance \(L\). If the back EMF is 1 volt when the current changes at a rate of one amp per metre, the coefficient of self inductance is 1 henry. There are four basic factors of inductor construction determining the amount of inductance created. These factors all dictate inductance by affecting how much magnetic field flux will develop for a given amount of magnetic field force (current through the inductor’s wire coil): Number of Wire Wraps, or “Turns” in the Coil

Self induction. Self induction is induction of emf in a coil due to its own current change. Total flux N passing through a coil due to its own current is proportional to the current and is given as N = L i where L is called coefficient of self induction or inductance.

Physically, the inductance L is a measure of an inductor’s “resistance” to the change of current; the larger the value of L, the lower the rate of change of current.

In practice, the inductance of coils with l > r can be calcula-ted with greater accuracy by an approximation formula

Coefficient of mutual induction I P is the current in coil P and φ s is the magnetic flux linked with coil S due to the current in coil P. where M is a constant of proportionality and is called the coefficient of mutual induction or mutual inductance between the two coils. So when the entire flux in one coil links with the other, the coupling coefficient is maximum. The maximum value of k is unity. Thus when k = 1, the coupled coils are called tightly or perfectly coupled coils. Also the mutual inductance between the two coils is maximum with k =1. The maximum value of the mutual inductance is given by Corrected Inductance is Base Inductance value with round wire corrections and frequency correction included. The single turn formula does not require round wire corrections. 7. K L is Nagaoka's field non-uniformity coefficient, calculated using Lorenz's elliptic integral formula. 8.
