本文描述了大块超导体在变化磁场中的行为。磁模型与实验结果一起描述，解释和描述的行为时，超导块材受到变化的磁场。我们演示了如何的行为是依赖于在字段中的扰动的幅度和周期。我们使用的模型已经使用Comsol™ pde求解器实现。这是一个完全集成的模型，它使用可变热源来调节磁路，从而实现磁通泵送。Comsol™用于解决后可视化，模型与实验结果一起展示，支持并确认了模型的结论。
This paper describes the behaviour of bulk superconductors when subjected to a varying magnetic field. A magnetic model is described together with experimental results which explain and describe the behaviour of superconducting bulks when subjected to varying magnetic fields. We demonstrate how the behaviour is dependent on the magnitude and period of the perturbations in the fields. The model which we use has been implemented using the Comsol™ pde solver. It is a fully integrated model which uses a variable heat source to regulate the magnetic circuit and thereby to achieve flux pumping. Comsol™ is used for post solution visualization and the model is presented alongside experimental results which support and confirm the conclusions from the model.
