Problem

Two coils have a mutual inductance of 0.50 H0.50\,\text{H}. The current in the primary varies with time as Ip=I0sin⁡(100πt)I_p = I_0 \sin(100\pi t) A, where I0=2.0 AI_0 = 2.0\,\text{A} and tt is in seconds. (i) Write the expression for the instantaneous emf induced in the secondary coil. (ii) Hence, determine the maximum magnitude of the induced emf.
