## The dees are provided with the current, which in turn will produce magnetic field other that the provided external magnetic field. will there be any effect of this magnetic field created by the dees on the motion of the particle inside the cyclotron? If yes then explain, if not explain why not?   also,   how is the particle revolution and the change in polarity synchronised?   please answer both the questions separately
