A rod of length L and resistance r rotates about one end with angular velocity ω as shown in the figure, its other end touches a conducting ring of negligible resistance. A resistance R is connected between the centre and periphery. There is a uniform magnetic field B directed as shown in the figure. Find the current in resistance R.
