Anybody tell me clear Working of …

1. As the current flows through coil in anticlockwise direction (d  c  b  a), the force is experienced by arms ba and dc.
2. Applying Fleming's left hand rule, ba experiences a force upwards and dc experiences a force downwards.
3. The coil abcd experiences two parallel, equal and oppositely directed forces. The coil rotates in clockwise direction about its axle.
4. Split rings C₁ and C₂ move along with the coil. After half the rotation of the coil, C₁ and C₂ get interchanged. C1 is now in touch with Brush B₂ and C₂ is now in touch with brush B1. (See Fig. (ii) of electric motor.)
5. The direction of the current in the coil continues to be anticlockwise. However on comparing the two fig., the direction of current in arms ab and cd has reversed.
6. ab part of the coil experiences a downward force and cd experiences an upward force. The coil continues its clockwise motion under the effect of these opposite, equal and parallel forces.
7. Thus the electrical energy from the battery has been converted into the continuous mechanical rotational motion of the coil in a motor.
