I am working on a project requiring Bluetooth capability. In order to make it convenient, it would be great to have a magnet in order for it to stick to things. I was just wondering if it is possible to use a magnet without damaging or affecting the electronics. Is there a magnet type that could be considered?
A magnet produces a static magnetic field (or even if you moved it as fast as you could, an extremely steady one), so that doesn't interfere at all with radio waves.
You'd be getting into trouble if your magnet was so strong that it lead to nonlinear effects. But unless you plan to affix your bluetooth device using an MRI, I doubt you'll be able to measure these effects without a lot of research budget at all.
