求翻译：Metal detector is based on the principle of electromagnetic induction work coil. When an alternating current through the coil, the coil is formed around an alternating electromagnetic field, electromagnetic induction and medium permeability, coil, the coil current area and from the coil center distance relation. When t是什么意思？ 待解决

金属探测器基于电磁线圈工作的原则。当通过线圈的交流电时，线圈被形成交变电磁场、 电磁诱导和渗透、 线圈线圈当前区域周围和从线圈中心距离关系。无金属，磁感应强度的有效检测范围的线圈时仍然不变，介质渗透性真空 (非金属相对渗透率 = 1） ；当线圈是有效检测范围的铁磁金属材料，由于相对渗透率的铁磁金属大于 1，可以使介质渗透性改变，导致周围磁感应强度变化的线圈。另一方面，在金属导体的交变磁场会产生自己封闭的涡 (涡流）
