Sounds to me your method worked fine. I also have one of those small telescoping wand magnets that i use sometimes to pick pins and small bits of metal. It works too but I would be hesitant to use around computer parts. I just ordered myself some very fine tipped tweezers and am anxious to get them so I can see how well they work. I think I could use my magnet wand on some areas of my machines like the bobbin areas.
