M = Mutual Inductance
M = k*(L1*L2)^1/2
M = 0.65(10)^1/2
M = 2uH
M = k*(L1*L2)^1/2
M = 0.65(10)^1/2
M = 2uH

This formula is correct. It is related to coupling coefficient.

M=MUTUAL Inductance
M=K(L1*L2)^1/2
M=K(L1*L2)^1/2

K=M/sqrt(L1*L2)...............(According to coefficient of coupling)
i.e M=K*sqrt(L1*L2)
=.65*sqrt(5*10)
=.65*3.15
=2.055
Appox=2
i.e M=K*sqrt(L1*L2)
=.65*sqrt(5*10)
=.65*3.15
=2.055
Appox=2
