A conducting rod of length l slides at constant velocity v on two parallel conducting rails A square loop of side l having resistance R moves with constant velocity v A straight horizontal conductor of length l and mass_ m slides down on two smooth conducting fixed parallel rails set inclined at an angle theta to the horizontal as shown in figure The top end of the bar are connected with a capacitor of capacitance C. The system is placed in a uniform magnetic field Twelve wires of equal lengths are connected in the form of skelton cube which is moving with a velocity v in the direction of magnetic field B.find the emf in each arm of cube. Two long parallel horizontal rails a
