There is a closed ring immersed in a uniform magnetic field. It's plane is perpendicular to the magnetic field. The magnetic field is inwards. A metal rod is attatched to the centre and to the perifery of the circle and is rotated about the centre (fixed) with an angular frequency w. Now, induction takes place as the electrons tend to drift away but due to the centre becoming posetive the electrons are held back, there will be instantaneous current and then, the state becomes steady. Now, there will be an emf produced between the centre and the periferry. Now, answer the following:

1) Define induced current and induced emf.
2) Is electrical induction possible? (independently)
3) Is magnetic induction possible?(independently)
4) Define electromagnetic induction.
5) What kind of induction is shown above in the circle-rod system?
