This formula is correct. It is related to coupling coefficient.
Santosh said:

M=k*sqrt(L1*L2) this is according to the coupling coefficent

M = K*^1/2(L1*L2).
So M = 0.65*3.15.
= approx 2micro H
So M = 0.65*3.15.
= approx 2micro H

I did not understand the formula used to data clearly.

Formula is
Coupling Coefficient K=M/(sqrt(L1*L2))
Coupling Coefficient K=M/(sqrt(L1*L2))

I can't understand this example, please explain.

The co-efficient of coupling K=M/(SqrtL1*L2).

M = K(L1 * L2)^1/2,
M = 0.65(10)^1/2,
M = 2UH.
M = 0.65(10)^1/2,
M = 2UH.

The correct formulae are k=M/(L1*L2)^1/2.
