Is any physical explanation of this effect?

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.
 
I was using the Smith chart to determine the input impedance of a transmission line that has a reflection from the load. One can do this if one knows the characteristic impedance Zo, the degree of mismatch of the load ZL and the length of the transmission line in wavelengths. However, my question is: Consider the input impedance of a wave which appears back at the source after reflection from the load and has traveled for some fraction of a wavelength. The impedance of this wave as it...
