Vortex dynamics, current density, and free energy curves in type II superconductors have been studied based on the Time Dependent Ginzburg-Landau (TDGL) model. The intensity of the normal material defect and its position were varied to determine the difference in the free energy curve of 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 in reaching the equilibrium state of superconducting material. This study can help determine the defect arrangement for effective pinning preparation in superconducting materials.
