Sooo.. for those of us that like to work in the shed.. and cant keep everything in pockets while rolling around under cars etc…. make a spot for your phone that is away from the work bench…
I just spent 30 minutes with lightly magmatic tweezers pulling metal filings out of my phones speaker..
Oppse.
Did the same think with a handie talkie. Had it clipped to my belt while grinding down some welds. Had to take the speaker out and pick all the filings out of it.
I have a electromagnet I built in highschool…. But wave a powerful magnet over a mobile phone…. hmm pass. Not 100% on what having some of the innards of a sensitive electronic device exposed to a strong magnetic charge may have..
