Calculate the mutual inductance between two coils when a current of

4\text{ A}

changes to

12\text{ A}

0.5\text{ s}

in the primary and induces an emf of

50\text{ mV}

in the secondary. Also, calculate the induced emf in the secondary if the current in the primary changes from

3\text{ A}

9\text{ A}

0.02\text{ s}
