Abstract: A device for measuring the thickness of films or coatings on bases wherein the film thickness is determined from the magnetic adhesive force of a permanent magnet on the surface of the film to be measured. The device includes a permanent magnet attached to an end of a lever arm mounted at its center of gravity, forming a rotary system which includes an electromagnet counterbalancing the permanent magnet. The magnetic adhesive force between the permanent magnet and film is overcome by the variable force of the magnetic field of the electromagnet acting on the lever arm of the rotary system, the value of which, as the permanent magnet is lifted off the film, is used as a measure of the film thickness. In the best mode of operation, this is accomplished by integrating the time required to raise the current applied to the electromagnet to the value which generates a magnetic field which overcomes the adhesive force between the film and permanent magnet.

A fourth embodiment adds a member which is drawn along the non-magnet tube by the magnet tube, and stays at its furthest extension on the non-magnet tube, due to a slight frictional load, when the magnet tube pulls off the material being tested.
