We developed a system for exposure of cultured cells to extremely low frequency (ELF) magnetic fields much stronger than those used in previous in vitro studies. The system consists of an electromagnet, a commercial incubator with a custom-designed door and a custom-designed shelf, and other components, and exposes cells in the incubator to ELF magnetic field. We confirmed that it has good performance characteristics in terms of field intensity, field uniformity, waveform, field stability, temperature uniformity, and temperature stability. Its features include: (1) strong ELF magnetic fields (at most, 170 mTRMS), (2) long-term exposure (at least, 5.5 h), and (3) variable frequencies (10-100 Hz). This exposure system is expected to contribute significantly to research on possible hazards of ELF magnetic fields.
我们开发了一种系统，用于将培养的细胞暴露于比以往体外研究中所使用的强度大得多的极低频（ELF）磁场中。该系统由一个电磁铁、一个带有定制设计门和定制设计搁板的商用培养箱以及其他组件组成，可使培养箱中的细胞暴露于ELF磁场中。我们证实，该系统在磁场强度、磁场均匀性、波形、磁场稳定性、温度均匀性和温度稳定性方面具有良好的性能特征。其特点包括：（1）强ELF磁场（最高可达170 mTRMS），（2）长期暴露（至少5.5小时），以及（3）可变频率（10 - 100 Hz）。这种暴露系统有望对ELF磁场可能存在的危害的研究做出重大贡献。
