A planar loop of wire rotates in a uniform magnetic field. Initially, at $\displaystyle \mathrm{t}=0$, the plane of the loop is perpendicular to the magnetic field. If it rotates with a period of $\displaystyle 10$ s about an axis in its plane then the magnitude of induced emf will be maximum and minimum, respectively at :
