Magnetostatic surface field measurement facility

Abstract : This report presents the analysis, design, and performance characteristics of an Radio Frequency Helmholtz coil facility. The facility was developed to measure the magnetic response of models up to two feet in size. Test measurements were made on metallic spheres and cylinders, and on a model F 106 aircraft over a 1-25 MHz frequency range corresponding to 20-520 kHz full scale. A large portion of the report is devoted to the relevant theoretical studies that include studies of the magnetostatic response of canonical shapes, both perfectly and imperfectly conducting.
