壞指南针如何修復-如何快速回復南北對換的指北針 how to fix/remagnetize compass needle

指北針/指南針有時無故突然南北方向對換了，紅針變了指南，亦有部分情形是磁針反應很慢，失去磁力，只要一塊強力磁石，(我是從電單車油箱袋拆出來，書局亦可買到)，不到一分鐘時間便完成。

A strong magnet is required to fix the wrong compass needle and bring it back to the original orientation. That is the red needle point to North. By following the procedure as shown in the  video, use a normal compass  to find out and mark the North pole and South pole of the strong magnet.
Then , follow the video, use the Southern pole of the strong magnet to re-magnetize the red color needle as North (ie. red needle point to the Northern direction), it might take several times.
