A novel concept of cloaking, concentration and transferring of the static magnetic fields by the combination effect of the superconductor (SC) and ferromagnet (FM) has been recently presented. The performance of these hybrid structures strongly depends on the properties of the involved materials as well as its geometrical parameters. In this work, we have practically demonstrated a magnetic hose, which is developed by a FM core wrapped by a SC layer. Meanwhile, a finite-element simulation with experimentally derived permeability of both SC and FM constituents was also established. Based on the verified simulation, further investigations were carried out to systematically examine the dependence of the transfer efficiency of the magnetic hose on its dimension and magnetic properties of the involved materials, both of which are difficult to be varied in practical case, especially for the magnetic properties.
