A wire loop enclosing a semi-circle of radius Ris located on the boundary of a uniform magnetic field of induction B. At timc t = 0, the loop is set into rotation with angular velocity angular `omega` about its axis 0, coinciding with a line vector B on the boundary as shown in the figure. The emf induced in the loop is
