Abstract

We have studied the orbits of magnetized particles around Hořava-Lifshitz black hole with mass \(M\) immersed in an asymptotically uniform magnetic field in the infrared approximation when \(\omega M^{2}\gg 1\). It is shown that magnetized particle’s orbit in Hořava-Lifshitz spacetime is different with compare to one in Schwarzschild spacetime due to the presence of additional terms related to the Kehagias-Sfetsos (KS) parameter \(\omega\). Using the Hamilton-Jacobi formalism, we have found the dependence of the area of stable circular orbits of the magnetized particle on dimensionless KS parameter \(\tilde{\omega}\) and have plotted them for several values of magnetic coupling parameter \(\beta\) as well as obtained the equations of motion of the magnetized particle. Moreover, we have studied the dependence of the collision of (magnetized, charged, non-charged) particles on KS parameter \(\omega\) for some fixed values of the magnetic coupling parameter \(\beta\).
