A stiffw ire bent into a semicircle of radius R is rotated at a frequency Jin a uniform magnetic field B. Calculate the amplitude and frequency of the induced voltage. If this circuit has negligible resistance and the internal resistance of the ammeter is `100Omega`, calculate the amplitude of induced current.
