We study the dynamics of spinning test particles orbiting a Kerr black hole by means of the Papapetrou equations. Using the linear perturbation method, the relations between the innermost stable circular orbits (ISCO) and the Kerr rotation parameters with fixed particles’ spins are given out. And, we find that the binding energy per unit rest mass of the ISCO increases remarkably when a large magnitude of spin exists. Also, we investigate the orbit of a spinning particle that falls radially into the central rotating black hole from infinity and compare it with nonspinning cases. Furthermore, we present the dynamical equation of spinning particles in Kerr spacetime using post-Newtonian expansion, and propose a possible highly precise method to test General Relativity by means of measuring the motion of the spinning particles.
