We have investigated the magnetic flux distribution of a Sm-Ba-Cu-O bulk superconductor using a Hall probe sensor in order to clarify the time and local dependence of the magnetic flux density. It was found that the magnetic flux distribution is affected by flux creep and the sweep rate of the applied field. We have also observed the local dependence of magnetization and compared it with the results of SQUID measurements.
