您好！您可以将接收线圈的“线圈激励”改为“电压”，并设置“线圈电压”为0 V。具体操作可以参考官网案例：//www.denkrieger.com/model/self-inductance-and-mutual-inductance-of-a-single-conductor-and-a-helical-coil-12679

请参考以下官网案例中的方法进行建模：

我又确认了一下，线圈的磁通没有增加是减小了，这能解释为什么电感减小，但是！！为什么加了铁芯之后线圈级联通量（磁通）会减小？线圈的面积没变磁感应强度增加，磁通应该增加才对。

您的报错与具体模型有关，建议联系技术支持：//www.denkrieger.com/support
