abstract = {{This study focused on the flux trapping of the superconducting cavity by measuring changes in the spatial magnetic field distribution for the Nb single-cell cavity using the magnetic field and temperature mapping system. The different external magnetic fields were applied when the cavity was vertically tested. The differences of magnetic field distribution were compared before and after flux trapping caused by quenches. The magnetic field mapping measured the magnetic field, including 3 axial directions, outside the equator of the cavity. Moreover, the local heating generated by the magnetic flux trapping was observed locally using temperature mapping. The result shows that the changes in the magnetic field distribution have the magnetic field components towards the quench location. In this presentation, the detail of experiments and results of the change of the magnetic field distribution and the local heating will be presented.}},
