The nonlinear one‐fluid system of equations is shown to adequately describe linear kinetic Alfven waves in a low‐β(β≪1) homogeneous plasma. It is demonstrated that energy of the plasma system is conserved. 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 salem ridge membership
