  In stochastic thermodynamics, significant attention has been given to
studying the statistical behavior of thermodynamic quantities such as heat and
work. However, fluctuations in other quantities, such as kinetic energy and
internal energy, can also exhibit intriguing statistical properties. In this
study, we investigate the fluctuations of kinetic energy within an initially
equilibrated underdamped Brownian particle subsequently exposed to a Lorentz
force, comprising both electric and magnetic fields. Providing insights through
the examination of the characteristic function, central moments, and kinetic
energy distribution.
