I just received a Mighty Mag in the mail today. I am planning to use it on my mini lathe to hold a dial indicator. While inspecting it and testing how strong the magnet was, I started to wonder if the magnet could harm my indicators. I’ve seen some indicators advertised as not being magnetic. Do I need to worry about a strong magnet damaging dial indicators like they can mechanical watches ?
Thanks
