摘要
推导了匀强磁场中通电悬链线形状方程，给出了形状方程的解析表达式．定义比例参数为磁场强度和电流乘积与质量线密度和重力加速度乘积的比值．当比例参数和悬链线宽度取特定值时，多种形状共存．
Abstract： The equations of catenary with current in the uniform magnetic field are derived. The analytical solutions are obtained. The parameter is defined as the ratio between the product of magnetic field and current and the line mass density and gravitational acceleration. Multi - configurations may coexist when the ratio parameter and the width of catenary take special values.
