  This paper explores the dynamics of both neutral as well as charged particles
orbiting near a rotating black hole in scalar-tensor-vector gravity. We study
the conditions for the particle to escape at the innermost stable circular
orbit. We investigate stability of orbits through effective potential and
Lyapunov exponent in the presence of magnetic field. The effective force acting
on particle is also discussed. We also study the center of mass energy of
particle collision near the horizon of this black hole. Finally, we compare our
results with the particle motion around Schwarzschild, Kerr and
Schwarzschild-MOG black holes. It is concluded that the external magnetic
field, spin parameter as well as dimensionless parameter of the theory have
strong effects on particle dynamics in modified gravity.
