Abstract: We found out that a pair of trapped magnetic field of high temperature superconducting bulk magnets is capable of floating the iron block in its space. And also, the gap space between the two HTS bulk magnets is very important to levitate the iron object. That is to say, if it tries to levitate smaller iron object in a constant gap space, the object will be attracted one side of HTS bulk magnet. Then, we conducted the improvement of this method to be able to levitate smaller iron object in a constant gap space. As a result, it was found that when an electromagnet, which uses the HTS bulk magnet magnetization, utilizes together with the trapped magnetic field of HTS bulk magnets, it is possible to levitate smaller iron object in constant gap space. And also the superimposed magnetic field, which composed of electromagnet and HTS bulk magnet, can create the constant magnetic field in the gap. By using this field, we found that magnetic particles such as iron sand can move in larger gap space.
