Two magneically coupled coils have self-inductances of 60mH and 9.6mH, respectively. The mutual inductance between the coils is 22.8mH.

a) What is the coefficient of coupling?

b) For these two coils, what is the largest value that M can have?

c) Assume that the physical structure of these coupled coils is such that P1 = P2, What is the turns ration N1/N2 if N1 is the number of turns on the 60mH coil?
