Nickel Thickness Gage

Source

The thickness of a nickel film can be determined by measuring the force required to pull a small magnet free of the surface; however, inconsistent and unreliable results were obtained with this type of measurement when the film was extremely thin and the surface slightly rough. The magnetic properties of nickel suggested that a reluctance technique of measurement could be used to determine the thickness of the nickel.
