Cyclotron Frequency from Charge, Mass, and Field Calculator

f_c = q · B / (2 · π · m).

Compute the cyclotron (gyromagnetic) frequency of a charged particle moving perpendicular to a uniform magnetic field B: f_c = q B / (2 π m). Independent of particle speed (non-relativistic). Also reports the angular cyclotron frequency ω_c = q B / m and the cyclotron period T = 1 / f_c.
