  The two apparently disparate phenomena, viz. the Klein tunneling and the
electric field driven topological phase transition(TPT), exhibited by the
silicene converge on the issue of the no change in the pseudo-spin. An ensuing
possibility is that the former, in the case of a normal/magnetic/normal
silicene junction, may be considered theoretically as a probe to ascertain the
onset of the latter. In this communication, we explore this option and
calculate the total transmission probability(TTP). We find that TPT is
characterized by a cusp in a plot of TTP as a function of the electric field.
