A pulsed magnetic field using a small coil can be applied generating strong magnetic field for magnetization of the high-T{sub}c superconductor (HTS). The magnetization using the pulsed magnetic field is done on the state of the zero field cooling. We examined optimum conditions for the pulsed field magnetization of the HTS. An optimum value of the pulsed field magnetization was confirmed. To predict the characteristics of the pulsed magnetic field to produce enough magnetization of the HTS, it is necessary to consider the time constant for the magnetic flux invasion and the flux flow at the decreasing process of the applied magnetic field. Moreover the relation between the pulsed magnetic field and the time constant of the magnetic flux invasion was explained by measurement of the pulsed field magnetization process.
