地球是一个巨大的磁场，人类生活在这样一个天然的磁场生物圈中，也相应地形成了人体的自身磁场。据测定，人体胸前的磁场为一个微高斯，相当于地磁强度的百万分之一；人体心脏、肺脏、大脑、肌肉和神经等都有强度不同的微弱磁场。所以说，人类赖以生存繁衍的环境离不开磁。但 The Earth is a huge magnetic field, and human beings live in such a natural magnetic biosphere, and accordingly form the body’s own magnetic field. It is determined that the human body’s chest is a micro-Gaussian magnetic field, equivalent to one millionth of the geomagnetic intensity; the human heart, lungs, brain, muscle and nerve all have weak magnetic fields of different intensities. Therefore, the environment in which mankind depends for its existence and development can not be separated from magnetism. but
