A rod of length `L` rotates in the form of a conical pendulum with an Angular velocity `omega ` about its axis as shown in Fig. 3.165. The rod makes an angle `theta` with the axis. The magnitude of the motional emf developed across the two emf of the rod is

the current in wire AB is ( ab is one of the diameters ) The radius of the circular conducting loop shown in figure is R. Magnetic field is decreasing at a constant rate alpha. Resistance per unit length of the loop is rho. Then
