Engineering Physics Annotation << Back Reduction of force of the magnetic levitation in the crossed magnetic fields I.A. Rudnev, Yu.S. Yermolaev We present the results of study of transverse ac magnetic fields influence on the levitation force arising between a bulk melt-textured HTSC YBCO superconducting sample and permanent NdFeB magnet. It is shown for the first time that the application of both impulse and alternative transverse magnetic fields results in considerable suppression of the levitation force value. The possible origin of observed phenomenon is discussed on the based of conception of critical state suppression in the high anisotropic two type superconductors. E-mail: iarudnev@mephi.ru
