Abstract :
This paper describes the design of a new d-c measuring instrument of the permanent-magnet moving-coil type. Alnico is utilized as a magnet alloy and the design factors involved in the application of this material to instrument design are discussed. A moving system for use with the Alnico magnet system is described and the resulting instrument performance summarized.
