Summary:This article deals with the magnetic resistance that arises in the cooled high temperature superconductor (HIS) bulk, dynamically interacting with a frequently perturbed flux of magnetic track employing homopolar permanent magnets (PM) arranged within an 'U'shaped loose iron core. The influence of flux perturbation on the magneto-dynamic maglev performance of HTS bulk is studied and tested by means of an experimental ring model device employing the same passive YBaCuO structure interacting with a magnetic track field differently perturbed by several iron plates radially and frequently distributed on the circular track. This experimental model device reproduces, by analogy, the magneto-dynamic behavior of a vehicle with HTS onboard riding above an uneven magnetic guideway. Finally, magnetic resistances and lift forces have been tested and the results are compared and discussed.
