You don't always find the wire or brier that did them in. It is almost always in the reticulum where your magnet went (reason magnets sometimes work when given after the fact and have a good track record if given as a hardware preventative)
The reticulum is easily identified by the net like pattern of shallow compartments on the inner surface and its small volume being a small pouch off the rumen located just behind the diaphragm. The rumenis identified by its lining of papillae (small finger like projections) and large volume. The omasum by its hard consistency, bean or ball shape and the ply or leaf like layers inside. The abomasum or true stomach is identifiable by its thin wall and velvety lining.
The diagnosis shown in the picture is peritonitis or infection of the abdominal cavity surrounding the organs.
It is amazing to me how a cow can wall off infection by forming adhesions and scar tissue between the surfaces of nearby organs close to the site of infection. The cow frequently goes about her business with nobody the wiser until the infection is under control or finally breaks loose and results in massive deadly contamination of the abdominal cavity.
The thin sheet of tissue with fatty areas interspersed with clear membrane is the omentum. It acts as sort of a slip sheet between organs and is one of the main actors in the process of walling off a source of infection like a nail or wire puncture or even a perforating ulcer.
