- The numerical solution of the time-dependent Ginzburg-Landau equations, was done to seek the dynamics of an external magnetic field applied into the type II superconductors. The resulting simulations are the form of the configuration of the order parameter, magnetic induction, Gibbs free energy and magnetization in the specimen. From the values of the order parameter configurations, the variations of an external magnetic field penetration into type II superconductor are observed. Meanwhile from the Gibbs free energy, the contribution terms of Gibbs free energy (condensation energy, kinetic energy and field energy) are monitored. In the t < 7 2 I D , the Gibbs free energy is contributed dominantly by the condensation energy. The size variations of the superconductor in this research as 8 x 8 .1,2 , 16 x 16 22 , 32 x 32 22 , and 64 x 64 22 , while variations of an external magnetic field 1.0 He , 1.2 He , 1.4 He , 1.6 He , 1.8 11c. dan 2.0 He . The values of Gibbs free energy are increase as the superconductor sizes are increase. However, the values of magnetizations are decrease as the superconductor sizes are increase. As an external magnetic field is increased, the rate time to reach the transition phase is faster while the values of magnetization are increase.
