Problem

In a system of two coaxial solenoids, the current in the primary varies with time as

I_p = 5t

A, where

t

is in seconds (

0 \le t \le 2\,\text{s}

). If the mutual inductance between the coils is

0.20\,\text{H}

, find the magnitude of the emf induced in the secondary at

t = 1.0\,\text{s}
