A magnetic field is an often-encountered physical environment that can affect many processes, including chemical, physical, and biochemical processes. Utilization of magnetic fields is thus very helpful in a wide variety of applications, such as scientific research in various disciplines, materials processing (e.g., crystal growth and separation) in industry, and nuclear fusion. There are many different types of magnetic fields generated by different magnets, such as superconducting magnets, electromagnets, hybrid magnets, pulsed magnets, and permanent magnets. In this paper, we introduce a newly designed periodic magnetic field generated by rotating permanent magnet pairs. Preliminary tests showed that the periodic magnetic field is valuable in water evaporation, silver deposition, and protein crystallization. Apparently, in such a new environment that can generate a periodic magnetic field, a periodic force field will also be simultaneously generated on the sample. Further work shall be carried out to explore the potential applications of this magnetic field.
磁场是一种经常遇到的物理环境，它可以影响许多过程，包括化学、物理和生物化学过程。因此，磁场的利用在各种各样的应用中非常有帮助，例如各学科的科学研究、工业中的材料加工（如晶体生长和分离）以及核聚变。不同的磁体可以产生许多不同类型的磁场，如超导磁体、电磁体、混合磁体、脉冲磁体和永久磁体。在本文中，我们介绍了一种新设计的由旋转永磁体对产生的周期性磁场。初步测试表明，该周期性磁场在水蒸发、银沉积和蛋白质结晶方面具有重要价值。显然，在这样一个能够产生周期性磁场的新环境中，样品上也会同时产生一个周期性力场。应进一步开展工作以探索该磁场的潜在应用。
