It is known that J_c varies depending on various conditions of pins that pin the magnetic flux lines in the superconductor under the transverse magnetic field. On the other hand, the TDGL equation is used as a phenomenological model capable of describing nonstationary superconductivity. Therefore, in this research, Numerically solving the three-dimensional TDGL equation using the approximation in a thin line visually expresses the motion of the quantized magnetic flux line in the superconductor under the transverse magnetic field, and investigate the E-J property and the J_c-B property.
