  "main_findings": "The authors designed and built a low-frequency pulsed strong magnetic field generator producing pulsed magnetic fields with intensity 0.1–2.5 T and adjustable pulse intervals. The device is described as easy to operate, reliable, and capable of steady long-term operation, and it has been used in experiments on biological effects of electromagnetics.",
