Gyroradius equation

WebEquation (3), with ɛ 0 ∂E/∂t neglected, relates currents and magnetic field structure. For example, it tells us that a change in magnetic field strength ΔB across a plane perpendicular to B must be associated with a current within the plane across which B changes. 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. In SI units, the non-relativistic gyroradius is given by The angular frequency of this circular motion is known as the gyrofrequency, or cyclotron frequency, and can be expressed as
