How to Calculate Induced EMF in Mutual Inductance?

[RwandaGloria]

Homework Statement

Two magnetically coupled could have a mutual inductance of 32mH. What is the average emf induced in one if the current in one if the current through the other changes from 3 to 15mA in 0.004s. Given that the coil has the number of turns in another. Calculate the inductance in each coil. Thank you.

Relevant Equations

average induced emf= 96x10^-3

I have gotten my average induced emf to be 96 x 10^-3V using the formula, e=Nx(∆I)/t but the problem lies in calculating the inductances.

Your phraseology is so poor that I have no idea what your question really is.
In general: what is the induced emf in one winding if the other winding experiences a given rate of change of current?
