This may sound like a silly question, but it got me thinking.
Apart from my lab at work, I have an electronic workbench at home. Most of my components are stored in small, plastic cylindrical jars (imagine the ones used for storing medical pills, something like that). I have a lot of those so I store all my resistors, capacitors and small package ICs in those containers. The problem is that the containers are all around the place, and even keeping them in a boxes makes it hard to find anything.
So my idea was to glue a small permanent magnet at the bottom of each jar and then put them on a metal surface (like a white board, or just a metal bar mounted on the wall).
However I was wondering if the magnet would have an impact on the components inside the jars. I had cases where transistor leads were attracted by magnets (no idea why, since they are supposed to be copper). I was about other drawbacks of such a solution, like maybe the components could get magnetised and would attract each other when assembling a PCB - that would be annoying.
So... Could you share your concerns regarding such a solution? Should I worry about the magnetic field?
