explain the working of electric motor in points
Answers
Electric motors involve rotating coils of wire which are driven by the magnetic force exerted by a magnetic field on an electric current. They transform electrical energy into mechanical energy.
The basic idea of an electric motor is really simple: you put electricity into it at one end and an axle (metal rod) rotates at the other end giving you the power to drive a machine of some kind. ... When an electric current starts to creep along a wire, it creates a magnetic field all around it.
In a basic DC motor, an armature is placed in between magnetic poles. ... In the coil, the current flows from A to B and the magnetic field is from north to south. Applying Fleming left hand rule, the direction of thumb pointsupwards, hence, the segment AB will tend to move upward, with a certain force.
