Vortex dynamics in the type-II superconductor have been investigated based on the TDGL (Time-Dependent Ginzburg-Landau) model. The variation of pinning position in the form of normal material defect is varied to determine the free energy density in the material when subjected to an external magnetic field. The curves of each energy term in the Ginzburg-Landau energy equation provide information about the dynamics of the vortex until it reaches an equilibrium state. In addition, the effect of placing the defect position in overcoming the dissipation effect in the form of potential differential fluctuations is also discussed. © 2020 Author(s).
