The cyclotron consists of two dees in strong magnetic field where oscillating electric field is applied from
an oscillator.
In this, magnetic field is perpendicular to electric field which exists only across the gap between the dees.
The charged particle gets accelerated, while crossing the gap and moves along the circular paths with
radius r = mv /q B
As charged particle is accelerated while crossing the gap, its kinetic energy increases which increases the
radius of circular path keeping frequency of revolution unchanged till mass remains constant.
The frequency of cyclotron described in q semicircular path with T as period of oscillating electric field will be
f=qB/2πm

Hello Students,
Physics is the most crucial subject for all the students of class 11th, 12th and also for the students who are preparing for NEET or JEE. Physics is very important to understand many higher level concepts, which are derived from the concepts that we learn in class 11th and 12th.
So better understanding of all the concepts in physics is very necessary, not only to get good marks in physics exam but also to learn physics more effectively.
