The gyroradius (also known as radius of gyrationLarmor radius or cyclotron radius) is the radius of the circular motion of a charged particle in the presence of a uniform magnetic field. In SI units, the non-relativistic gyroradius is given by

where  is the mass of the particle,  is the component of the velocity perpendicular to the direction of the magnetic field,  is the electric charge of the particle, and  is the strength of the magnetic field.[1]

The angular frequency of this circular motion is known as the gyrofrequency, or cyclotron frequency, and can be expressed as

in units of radians/second.[1]
