1.	In a d.c. motor why must the current to the coil be reversed twice during each rotation?
Answer» On changing the direction of the current, repulsion takes place between the coil and the pole.\xa0It is relevant to reverse the coil of the motor because if not done the coil shall reach the other pole of the magnet and the motor will stop.\xa0If change in direction the method of repulsion and attraction takes place.
