Answer 2

Answer:

Explanation:

THE ABOVE DIAGRAM IS ELECTRIC MOTOR . ELECRTRIC MOTOR COVERTS ELECTRICAL ENERGY INTO MECHANICAL ENERGY .

a) : THE MOTOR WORKS ON THE PRINCIPLE THAT WHEN A RECTANGULAR COIL IS PLACED IN A MAGNETIC FIELD AND CURRENT IS PASSED THROUGH IT , A FORCE ACTS  ON THE COIL WHICH ROTATES IT CONTINOUSLY . WHEN THE COIL ROTATES , THE AXILE ATTACHED TO IT ALSO ROTATES  . THE TURNING EFFECT IS CALLED AS ''TORQUE''.

b) :  THE SIDES AB AND CD OF THE COIL ARE KEPT PERPENDICULAR TO THE DIRECTION OF MAGNETIC FIELD BETWEEN THE POLES OF THE MAGNET .  THE FORCE ON SIDE AB  OF THE COIL IS IN THE DOWNWARD  DIRECTION . DUE TO THIS SIDE AB IS PUSHED DOWN . AFTER HALF ROTATION  AB COMES ON RIGHT SIDE. CD IS ON LEFT WITH DOWNWARD FORCE AND AB ON RIGHT SIDE WITH UPWARD FORCE . DUE TO THIS CD PUSHES DOWN AND AB PUSHES UP

C) :  A DEVICE WHICH REVERSES THE  DIRECTION OF A CURRENT THROUGH A CIRCUIT IS CALLED "COMMUTATOR" .

IN ELECTRIC MOTOR SPLIT RINGS ACTS AS COMMUTATOR .
