摘　　要：介绍了强磁性磁链在弱磁场条件下产生二次磁场的特性 ,计算出磁链的二次磁场值 ,估算了实际分选时由磁铁矿物构成的磁链在端面处的磁场力量级以及磁链的二次磁场有效作用距离。The characteristics of the secondary magnetic field induced by the strongly magnetic chain in low intensity field are described and the value of the secondary magnetic field is calculated.The order of magnitude of the magnetic field on the end surface of the magnetic chain made of magnetic minerals in real separation and the effective distance of the secondary magnetic field are estimated.
