Query: Dynamics of Particles Around a Regular Black Hole with Nonlinear
  Electrodynamics   We investigate the dynamics of a charged particle being kicked off from its
circular orbit around a regular black hole by an incoming massive particle in
the presence of magnetic field. The resulting escape velocity, escape energy
and the effective potential is analyzed. It is shown that the presence of even
a very weak magnetic field helps the charged particles in escaping the
gravitational field of the black hole. Moreover the effective force acting on
the particle visibly reduces with distance. Thus particle near the black hole
will experience higher effective force as compared to when it is far away.
