Pliers Turned Magnets, How Do They Work?
I had to cut some metal today, and was happy to be able to use the angle grinder that was given to me recently by a kind co-worker. Sparks flew and my workbench was soon covered in a fine layer of iron filings. I went to grab my trusty pliers, and noticed that the ends of the handles had little afros made of iron filings. How did this happen?! It's not like I magnetized them on purpose, and can't recollect ever storing them near anything magnetic. Could it be that from the friction or proximity to the angle grinder's motor that the filings themselves became electrically charged? Anyone care to shed light on this? One thing I know is that these guys won't be able to give me a satisfactory answer.
