Magnetic compensation can help achieve long-term ground-based microgravity environments for cryogenic fluids. However, existing studies often create compensated-gravity regions too small to replicate fluid behaviors in space conditions. This study developed a magnetically compensated system capable of generating a low-gravity region with a volume of 0.88 L for liquid oxygen. Single-bubble dynamics were used to evaluate gravity levels as low as 0.033 g 0 . The system allows visualization of microscopic fluid behavior with up to 6.13× magnification and an adjustable field of view ranging from 1 to 200 mm.
