Any danger with magnets and electronics

[OLEJOE]

There’s not a lot of effort to stick a magnet on a filter. The manufacturer puts magnets in and on every other system in the truck and doesn’t put a magnetic drain plug on the engine. I cut all of my filters after use and thought it might capture some of the smaller ferrous particles the filter doesn’t. Just wondering if there would be any chance of the electronics on the engine having a problem with the magnetic field intruding.
