The paper contains a brief, illustrated description of the Magnetic Model Facility at the U.S. Naval Ordnance Laboratory. The primary emphasis is on the use of the Facility in conducting magnetic ship model studies. First, a synopsis is given of techniques for designing magnetic ship models and of problems associated with scaling magnetic characteristics of ferrous items. Next, a description is given of the Facility including: the coil system, the model range, the digital recording system, and other major items of equipment. Finally, a discussion is included on techniques of automated data acquisition and data analysis.
