Overview
Cyclotron frequency is the frequency of a charged particle moving perpendicular to a uniform magnetic field. The particle follows a circular path due to the Lorentz force.
💡
Pro Tips
The frequency does not depend on the speed or radius of the particle (non-relativistic).
Charge is in Coulombs (C), Mass in Kilograms (kg), and Magnetic Field in Tesla (T).
Standard particles like electrons and protons have preset values.

Fun Facts
"The cyclotron frequency is what allows particle accelerators (cyclotrons) to work."
"It is a key principle in Mass Spectrometry, used to identify chemical substances."
"In the Earth's ionosphere, electrons and ions spiral around geomagnetic field lines at their cyclotron frequencies."
