The working of an electric motor and generator

Click For Summary
SUMMARY

The discussion centers on the fundamental principles of electric motors and generators, specifically how mechanical energy is converted to electrical energy and vice versa. The key mechanism involves the interaction between a rotating coil and a magnetic field, where the coil cuts through magnetic lines of force, inducing an electromotive force (EMF) according to Faraday's law of electromagnetic induction. The conversation highlights the importance of Fleming's Right-Hand Rule in understanding the direction of induced current in generators.

I have a very silly question . I know how an electric motor and generator work; the changing magnetic flux and current flow causes the coil to rotate etc. and it generates mechanical or electrical energy.

M question is how does turning of the coil generate mechanical energy from electrical energy in a motor and electrical energy from mechanical energy in a generator?
 
Physics news on Phys.org
I think you question is a little unclear. Are you asking what relationship exists between mechanical and electrical energy which allows them to be interchangeable?
 
What I'm trying to ask is how does turning a coil create electricity? I know how the coil turns but how does the turning go on to give electricity in a generator?

The wire in the turning coil cuts the field from a permanent magnet at right angles, which initiates electron movement in the wire. There is loads about this on the internet.
 
Look up Flemings right hand rule.
