KORPINAR, Talat  e  DEMIRKOL, Rıdvan Cem. Magnetic motion of spherical frictional charged particles on the unit sphere. Rev. mex. fis. [online]. 2019, vol.65, n.5, pp.496-502.  Epub 23-Abr-2020. ISSN 0035-001X.  https://doi.org/10.31349/revmexfis.65.496.

Mathematically, the unit sphere 𝕊2 is described in an ordinary space with positive curvature. In this study, we aim to present the manipulation of a spherical charged particle in a continuous motion with a magnetic field on the sphere 𝕊2 while it is exposed to a frictional force. In other words, we effort to derive the exact geometric characterization for the spherical charged particle under the influence of a frictional force field on the unit 2-sphere. This approach also helps to discover some physical and kinematical characterizations belonging to the particle such as the magnetic motion, the torque, the potential energy functional, and the Poynting vector.
