"Mag"? As in magnetic field detection?
In P#606 I asked "does submersible technology exist that is capable of locating a stainless steel component (which may be made of an SS with properties that are not strongly responsive to magnetic field detection) at some depth below the surface of the sea bed amidst a debris field made up of aluminum and other metallic objects?"
The magnetic properties of stainless steel alloys vary significantly according to elements added to the alloy family. The SS pots in my cupboard are NOT responsive to a magnet, the trim on my vintage car IS responsive.
