目前，在实际应用中，用户需要将电磁耦合能量输出装置吸附在目标受电装置的外壳上，通过电磁耦合进行能量输入。比如使用无线充电器给笔记本或手机进行无线充电。而当前采用磁铁吸附的方案，都是将磁铁设置在线圈模组的外周边缘，再通过磁铁与目标受电装置的磁吸作用，而固定目标受电装置，从而便于目标受电装置与线圈之间进行无线充电作业。磁铁一般是成对设置，并绕线圈模组的外周设置有多对磁铁。

请参阅图1及图3，在一个实施例中，固定环14沿背离线圈21中心位置的方向的宽度大于第一磁条11沿背离线圈21中心位置方向的宽度。通过适当增大固定环14的宽度，使固定环14的宽度大于第一磁条11的宽度，而根据第一磁条11磁感线的分布，固定环14可以尽量降低第一磁条11沿宽度方向的磁场，从而有效降低第一磁条11的整体磁场对线圈21的干扰。
在一个实施例中，固定环14沿背离线圈21中心位置方向的宽度大于第二磁条12沿背离线圈21中心位置的方向的宽度。通过适当增大固定环14的宽度，使固定环14的宽度大于第二磁条12的宽度，而根据第二磁条12磁感线的分布，固定环14可以尽量降低第二磁条12沿宽度方向的磁场，从而有效降低第二磁条12的整体磁场对线圈21的干扰。
可选地，固定环14的宽度范围为0.6~2.0mm。
请参阅图3及图5，在一个实施例中，第一磁条11和第二磁条12的长度方向绕线圈21的中心位置呈弧线布置。可选地，第一磁条11和第二磁条12为弧形磁条，且第一磁条11和第二磁条12的弯曲方向与线圈21的周向一致。
在一个实施例中，第一磁条11和第二磁条12的长度方向绕线圈21的中心位置均呈直线布置。可选地，第一磁条11和第二磁条12为直线磁条。
在一个实施例中，各磁体组件13依次连接，且至少有一磁吸组件和与其相邻的另一磁吸组件间隔设置，并共同形成第一泄磁缺口131。通过在磁吸结构10的布置路径上设置第一泄磁缺口131，各磁吸结构10的部分磁场可以从第一泄磁缺口131释放出去，从而降低各磁吸结构10的磁场对线圈21的影响。
请参阅图3及图5，在一个实施例中，各磁吸组件绕线圈21的中心位置依次间隔布置，且任意相邻的两磁吸结构10之间均形成第二泄磁缺口132。通过在磁吸结构10的布置路径上设置第二泄磁缺口132，各磁吸结构10的部分磁场可以从第二泄磁缺口132释放出去，从而降低各磁吸结构10的磁场对线圈21的影响。
在一个实施例中，固定环14上开设有第三泄磁缺口133。通过在磁吸结构10的布置路径上设置第三泄磁缺口133，各磁吸结构10的部分磁场可以从第三泄磁缺口133释放出去，从而降低各磁吸结构10的磁场对线圈21的影响。
请参阅图3及图5，在一个实施例中，磁吸装置100还包括用于固定磁吸结构10的定位环50，定位环50的环面开设有限位槽51，限位槽51绕线圈21的中心位置圆周布置，磁吸结构10部分容置于限位槽51。可选地，定位环50位于磁吸结构10的下方，通过限位槽51可以使各磁吸结构10保持稳定，不会相对线圈21发生位移，从而有利于磁吸装置100的可靠性。
请参阅图6和图7，本申请还提出了一种无线充电器200，该无线充电器200包括磁吸装置100  ，该磁吸装置100    的具体结构参照上述实施例，由于本无线充电器200采用了上述所有实施例的全部技术方案，因此同样具有上述实施例的技术方案所带来的所有有益效果，在此不再一一赘述。
在一个实施例中，无线充电器200还包括壳体结构30，壳体结构30具体有安置腔321，磁吸装置100 位于安置腔321，壳体结构30设有供电子设备放置的充电面311。
