Someone hasnt read the previous posts... we already stated that ideia.

Same. You didnt read properly (imo).

Like, powerful. Not a pretty small magnet. As stated after :

Again, i fail to see what's the problem. Can you garantee that it wont have any considerable effects in a large time delta? I cant, because i havent tested. I felt like giving fair warning to certain effects, even if they dont really have a considerable interferance. And as i said , in theory, it would work (translated: it would probably be negligable).
>How strong a magnet are you using, for god's sake?
It was an industrial setting , very large diameters . All the sensing was with electromagnetic displacement.
