if the magnet were held fixed中的fixed是主语（the magnet）的补语；主语补语是由主动语态中的宾语补足语变化而来的.比如if the magnet were held fixed这句话如果使用主动语态,我们可以这样说：if we(主语) hold（谓语） the magnet（宾语） fixed（宾语补足语）.但是在科技文章中,一般是没有动作的执行者的,也就是说句子的主语一般不会是“人”,所以被动语态用得就多.
这句话里不用to be fixed是因为不定式一般表示将要做的动作.if the magnet were held fixed的意思是“如果将磁体/铁固定”,而不是if the magnet were held to be fixed“如果磁体/铁将要（被）固定”吧.（我对这种专业性的内容是外行,见笑.）
