What is the self inductance?

Self-inductance is the tendency of a coil to resist changes in current in itself. Whenever current changes through a coil, they induce an EMF, which is proportional to the rate of change of current through the coil.

What is meant by flux linkage?

Flux linkage is the linking of the magnetic field with the conductors of a coil when the magnetic field passes through the loops of the coil, expressed as a value. The flux linkage of a coil is simply an alternative term for total flux, used for convenience in engineering applications.

What is called mutual inductance?

mutual inductance. noun. a measure of the mutual induction between two magnetically linked circuits, given as the ratio of the induced electromotive force to the rate of change of current producing it.

What is meant by self inductance and mutual inductance Class 12?

The phenomena in which an emf is induced in a coil due to change of current through the same coil is known as self Induction. Mutual Inductance: The phenomena in which an emf is induced in one coil due to change of current is the neighbouring coil is called mutual induction.

What is self induction write the unit of self induction?

The phenomenon in which emf is induced in a single isolated coil due to change of flux through the coil by means of varying the current through the same coil is called self inductance. S.I unit of inductance is Henry.

What is flux linkage in inductor?

We define the flux linkage  as the total flux passing through the surface bounded by the contour of the circuit carrying the current. Now we define inductance L as the ratio of the flux linkage to the current I generating the flux, This has the units of henrys (H), equal to a weber per amp.

What is mutual inductance class 12th?

In mutual inductance there are 2 coils, current is passed in one coil, as current increases there is change in the flux, and as aresult current is induced in the second coil. This induced current opposes the increase of the current in coil 1.

What is the relationship between self and mutual flux linkages?

The self and mutual flux linkages produced by a winding are proportional to the current in the winding: the ratio of flux linkage to the current that produces it is therefore a constant, and is defined as the inductance of the winding. The self inductance (L), is given by

What is the difference between self inductance and mutual inductance?

Difference between Self and Mutual Inductance. Self inductance is the characteristic of the coil itself. Mutual inductance is the characteristic of a pair of coils. The induced current opposes the decay of current in the coil when the main current in the coil decreases.

What is mutual induction and how to calculate it?

When there is a change in the current or magnetic flux linked with two coils an opposing electromotive force is produced across each coil, and this phenomenon is termed as Mutual Induction. The relation is given as: = I. = M I. Where M is termed as the mutual inductance of the two coils or the coefficient of the mutual inductance of the two coils.

What is the ratio of flux linkage to current that produces?

The ratio of flux linkage to the current that produces it is therefore a constant, and is defined as the inductance of the winding. The self inductance (L) is given by
