SUMMARY

The discussion focuses on calculating the induced electromotive force (emf) in mutual inductance using the formula e = N x (∆I)/t. The average induced emf calculated is 96 x 10^-3 V. The main challenge highlighted is determining the inductances involved in the calculation, particularly in relation to the rate of change of current in one winding affecting the other winding.

PREREQUISITES

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?
