On which principle does the electric generator work?

Electric generator is a device which converts mechanical work into electrical energy. The main point here to note is that a changing magnetic field can induce current in a conductor. Working of the generator:

•Inside the generator there is a conductor wire placed between fixed strong magnets.

•When mechanical rotation is provided to that wire the magnetic field associated with the wire changes.

•Those wire are already placed in strong magnetic field of a strong magnet.

•So, the motion of the wire changes the magnetic field and induce an electric current in the wire.

•The direction of induced current is determined by Fleming's right hand rule.
