Q. 2. A rectangular frame of wire is placed in a
uniform magnetic field directed outwards, normal
to the paper. AB is connected to a spring which is
stretched to A'B' and then released at time t = 0.
Explain qualitatively how induced e.m.f. in the
coil would vary with time. (Neglect damping of
oscillations of spring)
