Abstract: Supersymmetry is a well established concept in quantum mechanics. The prominent role is played by Witten model of N=2 supersymmetry, where Hamiltonian and supercharges are represented by matrix operators. We will show that the genuine superalgebraic structure can appear in a hidden form, in the systems where the fermionic degrees of freedom are absent. We will discuss a planar model of a spin-less particle in presence of a singular magnetic flux as an example.
