A square conducting loop is placed in the time varying magnetic field `((dB)/(dt)=+'ve constant')`.The centre of square coincides with axis of cylindrical region of magnetic field. The directions of induced electric field at point a, b and c.Consider a conducting circular loop placed in a magnetic field as shown in figure. When magnetic field changes with time, magnetic flux also changes and emf `e=-(dphi)/(dt)` is induced. If resistance of loop is R then induced current is `i=e/R`. For current, charges must have non–zero average velocity. Magnetic force cannot make the stationary charges to move. Actually there is an induced electric
