021. Electrodynamics (Cyclotron)
The cyclotron frequency is the frequency of a charged particle moving perpendicular to the direction of a constant magnetic field B.
Since the motion of a charged particle in the cyclotron is circular (because of a uniform magnetic field), we can calculate the cyclotron frequency by using the fact that the centripetal force equals the magnetic Lorentz force.
The above equation yields
Now, let’s look at the particles, Mass: Electric charge:
Therefore, their cyclotron frequencies in the same magnetic field,
