Abstract
An inspection device is provided for inspecting metallic objects extending in planar fashion, in particular sheets or walls. The inspection device is embodied as pipeline-impassable in particular by virtue of dispensing with at least one propulsion element that at least substantially fills an inner pipeline cross section. At least one functional unit is included for recording object information. At least one magnet unit is provided for magnetizing the object, the magnet unit including a plurality of magnets. The magnet unit has a plurality of segments each having at least one magnet, and the magnetization directions of segments adjoining one another are angled at least approximately by 90°, preferably by exactly 90°, relative to one another.
