Answer 2

—Construction:

—An electric generator consists of a rotating rectangular coil ABCD placed between the two poles of a permanent magnet the two ends of the coil are connected to two rings R1 and R2. the inner side of these rings are made insulated the two conducting stationary brushes B1 and B2 are kept pressed separately on the Rings R1 and R2. the outer ends of the two brushes are connected to the Galvanometer to show the flow of current.

—Working:

—The axle attached to the two Rings is rotated such that the arm AB moves up and the arm CD moves down by applying Fleming's right hand rule the induced current are set up in the these arms along the direction AB and CD. does an induced current flows in the direction ABCD. after half A rotation arm CD starts moving up and AB moving down as a result the direction of the induced current in both the arm change giving rise the net induced current in the direction DCBA.
