            When a charge particle moves in a magnetic field it bends into a circular path by an applied electric field. This concept is used in the cyclotron. Cyclotron is one of the earliest particle accelerators and is used to accelerate a moving charged particle by the applied electric field within the dees of the magnetic field region.

A moving charge in a cyclotron moves in a circular path under the influence of a constant magnetic field. The time period of the moving charge while completing a circular path is given as:
