I'd like to know if there is some magnet in the rotor or in the stator of the generator? Or neither of those (rotor & stator) need a magnet for the current to flow?

Best Answer
Depends on the type of electrical machine. All electrical machines can operate as Generators & Motors.
An electrical machine is an electrical <-> kinetic energy converter which utilises magnetic fields. The real question is by what means does the stator & rotor generate its magnetic field.
Types of electrical machines
Brushed DC
Induction Machine
Synchronous machine
Brushless DC or AC (these are sync machines)
Switched Reluctance
This is ignoring inside out machines.
For higher power generators however, national grid type machines, the topologies of these machines are wound rotor synchronous machines
