Can permanent magnets cause interference when placed alongside cables?
I know that interference can be induced from an alternating magnetic field e.g. transformer coils, but not too sure if a magnet in a fixed position would have the same effect?
There's a project that I have in mind that would use these magnets to secure a fabric around cables holding them together. A single 5mm button magnet on one edge of the material would attract to a metal disc embedded in the opposite edge. The cables will mainly connect to audio / visual equipment so it's important to avoid any interruptions or distortions of the signal along the way.
Can anybody help?
