Problem

Two coils have a mutual inductance of

0.50\,\text{H}

. The current in the primary varies with time as

I_p = I_0 \sin(100\pi t)

A, where

I_0 = 2.0\,\text{A}

and

t

is in seconds. a. (i) Write the expression for the instantaneous emf induced in the secondary coil. b. (ii) Hence, determine the maximum magnitude of the induced emf.
