利用15T、1500 μ m超导磁体产生的垂直磁场，研究了磁场对化学过程和物理过程的影响。1.樱桃番茄，水，青蛙，和其他磁悬浮的磁铁。塑料碎片被磁悬浮和分离。磁悬浮技术是一种用于抗磁性材料分离和抗磁性材料测量的有效技术。2.苯和水的光诱导热对流是由强磁场控制的。磁场是控制地球重力变化的一个方便工具。因为热量和浓度引起对流。a在磁场的辅助下，在通过硅酸盐花园反应制备的膜管中诱导3D-宏观手性。边界辅助磁流体力学机制的结果进行了解释。4我们提出了用强磁场对吗啡纳米棒、双金属纳米颗粒、微管蛋白等进行定向，表明磁场对纳米结构材料的定向是有用的。磁场对钛微粒表面光化学沉积钴离子的氧化态有影响，但其影响机理尚不清楚。6.磁场对介孔氧化硅中的光化学反应有显著的影响。其机理可用自由基对机制解释。这强烈地表明溶液在孔中的流体力学性质与在泡中的流体力学性质有很大的不同。结果表明，磁场是一种对材料科学有用的全新的物理环境。

Magnetic field effects (MFEs) on chemical and physical prooses were reseatched by using vertical magnetic fields generated by a 15 T and 1500 Pim superconducting magnet. 1. Cherry tomato, water, frog, and others are magnetically levitated by the magnet. Plastic chips are magnetically levitated and separated. Magnetic levitation is a useful technique fix separation of diamagnetic materials and cliainagnetic susoeptibility measurement. 2. Photoinchred thermal convection of benzene and water is controlled by application of high magnetic field. Magnetic field is a convenient tool for controlling Earth gravity-chiven phenomena sucb. as thermal and concentration induced convection. a With the aid of magnetic field, 3D-mcaphological chirality is induced in membrane tubes prepared by a silicate garden reaction. The results are explained by a boundary-assisted magnetohydrodynamics mechanism. 4 It is suggested to orient phorphine nanorods, tbiophene nanodusters, microtubulin and others using high magnetic fields, indicating that magnetic field is useful for nanostructure cont al. 5. Magnetic field influences oxidation state of cobalt ion photochemically deposited on titanium micropartides, though its mechanism is not clarified. 6. Photochemical reaction in mesoporous silica is significantly afiected by a magnetic field. Its mechanism is explainable by the radical pair mechanism. It is strongly suggested the hydrodynamics of the solution in the pore is very different from that in bullc. solution.In conclusion, it is shown that magnetic field is a brand-new physical environment useful for materials science.
