Explanation:
The device which convert the electrical energy into mechanical energy called electric motor.
Eg. Fan, Washing machine etc....
Construction....
• Armature coil
•Two magnet
•Axle
•Brushes ( B1 and B2)
•Split rings
• Battery
Working....
When the source battery is connected to the brushes the current while flow through the armature coil ABCD.
When the current flow in the armature coil ABCD then according to Fleming's left hand rule the force in AB is in the downward direction and similar in the armature coil CD, the force in the upward direction.
This is simultaneously phenomenon which rotate the motor ...
Hope this will help you....
