Is any physical explanation of this effect?
 
on Phys.org
Yes, A rotating magnet creates an AC magnetic field. That induces currents within the conductive surface which, by Lentz law, oppose the changes in the magnetic field, ergo, create a repelling force.
This principle has been applied to Maglev trains.
