Thank you for your input larry c & SteveFehr.

I understand the principles of inducing a current into a conductor that passes through a magnetic field.And i also understand that the stator acts as the electromagnet,
But the bit i don't understand is yes you now have a magnetic field set up in the stator for the rotor to cut right,but as the output from the generator is fed out the stator and not the rotor well then does the induced current in the rotor then get induced back into the stator then out?

Sorry about this i kind of thought i new this already!!
