In this paper, we have investigated the dynamics of magnetized particles around 4-D Einstein Gauss-Bonnet black hole immersed in an external asymptotically uniform magnetic field. We have shown that the magnetic interaction parameter responsible for circular orbits decreases for negative values of the Gauss-Bonnet parameter alpha and the range where magnetized particle's stable circular orbits are allowed increases for the positive values of the parameter alpha. The study of the collisions of magnetized, charged and neutral particles has shown that the center-of-mass energy of the particles increases in the presence of positive Gauss-Bonnet parameter. Finally, we show how the magnetic interaction and Gauss-Bonnet parameter may mimic the effect of rotation of the Kerr black hole giving the same ISCO radius for magnetized particles. Detailed analysis of the ISCO show that spin of Kerr black hole cannot be mimicked by the effects of magnetic interaction and the Gauss-Bonnet parameters when alpha < -4.37 and the spin parameter a > 0.237.
