A magnetic field of fair uniformity is obtained at the opening laminated C-shaped core of silicon alloy steel rigidly secured together and excited by d. c. or a. c. current. Description is given on a co-ordinates indicating set using a. c. current utilizing the variation of induced voltage in a coil placed at different positions in the opening of the core. With two units combined at right angle or any other angle, two-dimensional position is determined whereby the device can be used in position-and-motion-control system. An example is given of measuring the inclination of a plane by orthogonal co-ordinates. The author points out that the method is applicable to such as the automatic contour tracing mechanism which has recently been developed.
