If redox reactions occur on the surface of a motor and a current loop arises, then in a non-uniform magnetic field, in addition to the usual magnetic force, such a motor will also be affected by a chemical magnetic force. The chemical magnetic force belongs to the class of surface forces. Here we analyze for the first time the properties of chemical magnets, which consist of three dissimilar metals, as well as the magnetic field generated by a chemical magnet using paramagnetic nanoparticles. The results of the study show that the chemical magnetic force depends on the concentration and type of electrolyte, the pH of the solution, the temperature, and the structure of the chemical magnet. The results obtained can contribute to the creation of devices where chemical energy is directly converted into kinetic energy of motion.
如果氧化还原反应发生在电机表面并形成电流回路，那么在非均匀磁场中，除了通常的磁力外，这样的电机还会受到化学磁力的影响。化学磁力属于表面力的范畴。在此我们首次分析了由三种不同金属组成的化学磁体的特性，以及使用顺磁性纳米颗粒的化学磁体所产生的磁场。研究结果表明，化学磁力取决于电解质的浓度和类型、溶液的pH值、温度以及化学磁体的结构。所获得的结果有助于制造将化学能直接转化为运动动能的装置。
