Low magnetic induction intensity and high spatial penetration. The effective magnetic field intensity entering the human body is only a few gauss, but the spatial penetration can reach 60cm or even 100cm, which is more than ten times that of the ordinary magnetic therapy instrument. When the human body lies flat, the action range of 60cm can completely penetrate the whole human body, so that energy can deeply act on human cells, improve the quality of cell metabolism, activate cells, effectively promote blood circulation, improve microcirculation and comb the whole body. Moreover, it completely conforms to the international safety limit 100GS (gauss) proposed by the US Department of Energy, and is the most suitable healthy magnetic field environment for human physiological needs.
