# Gyroradius for a speed perpendicular to the magnetic field

## Description

The gyroradius (also known as radius of gyration, Larmor radius or cyclotron radius) is the radius of the circular motion of a charged particle in the presence of a uniform magnetic field.

Can be expressed as the radius of the orbit of a particle acting in a speed perpendicular to the magnetic field in a given gyrofrequency as shown in the formula.
