Basic Magnetic Quantities and the Measurement of the Magnetic Properties of Materials. NBS Monograph 47

摘要

The work of the Magnetic Measurements Section of the National Bureau of Standards includes (1) testing of specially prepared test specimens intended for use as standards for checking magnetic testing apparatus (2) investigation and development of magnetic testing apparatus (3) calibration of mutual inductors, test coils, and instruments for measuring magnetic fields, and (4) investigations in the field of magnetics such as studies of phenomena associated with nuclear magnetic resonance or the selection and testing of materials suitable to be used as standards of magnetic susceptibility. This monograph gives general information regarding magnetic quantities and units, the magnetic characteristics of various materials, and methods and apparatus commonly used in the Magnetic Measurements Section for magnetic testing.
