We report an anomalous reduction of the resistivity in certain YBCO ceramics, upon applying and consequently removing a low DC magnetic field. This phenomenon is observed just below Tc, while at lower temperatures the observed remanent resistivity is higher than the pristine, similar to the characteristic "field-on" resistivity hump. We show that this effect can be interpreted as originating in an intricate interplay of the frozen-in screening currents and the superconducting percolating current in the presence of the complex intergranular boundary system.
