electric motor converts electrical energy into mechanichal and vice verca in a e.generator
1. As the current flows through coil in anticlockwise direction (d c b a), the force is experienced by arms\xa0ba\xa0and\xa0dc.2. Applying Fleming\’s left hand rule,\xa0ba\xa0experiences a force upwards and\xa0dc\xa0experiences a force downwards.3. The coil\xa0abcd\xa0experiences two parallel, equal and oppositely directed forces. The coil rotates in clockwise direction about its axle.4. Split\xa0rings C1\xa0and C2\xa0move along with the coil. After half the rotation of the coil, C1\xa0and C2\xa0get interchanged. C1\xa0is now in touch with Brush B2\xa0and C2\xa0is 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\xa0ab\xa0and\xa0cd\xa0has reversed.6.\xa0ab\xa0part of the coil experiences a downward force and\xa0cd\xa0experiences 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.
