What is the mutual inductance of the two coils?

Definition: Mutual Inductance between the two coils is defined as the property of the coil due to which it opposes the change of current in the other coil, or you can say in the neighbouring coil.

What is the formula for mutual induction?

The constant of proportionality is called as mutual inductance. It can be written as. M 21 = N 2 ϕ 21 I 1 {{M}_{21}}=\frac{{{N}_{2}}{{\phi }_{21}}}{{{I}_{1}}} M21=I1N2ϕ21 … (2) The SI unit of inductance is henry (H)

What is mutual induction and mutual inductance?

When changing current in one coil induces an EMF in the other, the phenomenon is called mutual induction. The strength of the EMF induced depends on the mutual inductance of the pair of coils. unit of mutual inductance is Henry, the same as that of self-inductance.

What is mutual induction class 12th?

When two coils are placed near each other or brought near each other, the magnetic field of one coil gets linked to the other. This linking in the magnetic field leads to generation of voltage in the second coil called induced voltage. This is defined as mutual induction.

What is mutual induction define coefficient of mutual induction between two coils?

Coefficient of mutual induction is the ratio of induced e.m.f in secondary coil to the rate of change of current in primary coil.

How does the mutual inductance of a pair of coils change when?

i) Mutual inductance decreases when the distance between the coils is increased. On increasing the number of turns in the coil, mutual inductance also increases.

What is mutual inductance in physics?

When changing current in one coil induces an EMF in the other, the phenomenon is called mutual induction. The strength of the EMF induced depends on the mutual inductance of the pair of coils. The S.I. unit of mutual inductance is Henry, the same as that of self-inductance.

What do you mean mutual inductance of two nearby coils find an expression for mutual inductance of a solenoid coil system?

Mutual inductance, between two coils, is equal to the magnetic flux linked with one coil when a unit current is passed in the other coil. Alternatively, Magnetic field due to the current I2 in S2 is μ0n2I2. Therefore, resulting in flux linked with S1.

How do you find the coefficient of mutual inductance?

Formula used: M = εemf(dIdt), where M is the mutual inductance, ε is the EMF induced into the other coil and dIdt is the rate of change of current in the given coil. Mutual inductance is a measure of induction between two different circuits.

What is mutual induction define coefficient of mutual inductance and give its unit?

Hence the coefficient of mutual inductance is equal to the induced emf when decay rate of current in primary coil is unity. The unit of mutual inductance. M=AmpWeber​ or henry (H)

How does mutual inductance of a pair of coil change when a distance between coils is increased by two times?

(i) When the separation between the two coils is increased, the flux linked with the secondary due to the current in the primary, decreases. Hence the mutual inductance decreases.
