All magnetic fields loop. Even if you build a sphere out of magnets with only one pole facing out, the field will find a way to either link up with itself or the forces will cancel out.

Whatever you're building, it isn't a "monopole" and you're using the terminology incorrectly.

Also, you would actually need to crack open your ECU and run the magnet back and forth over the board to actually damage anything.

Take two neodimium magnets, Put a plate between them. E.g. Join the two magnets together; south to south with the plate in-between. This is what they call a monopole. Maybe, it should be called by another name. Since you mentioned that the magnets will not damage the ECU, is it enclosed in a faraday shield?

Its nice to have someone who knows his physics. Tnx for the info. Have a nice day.
