Abstract :
This paper, which deals with the experimental determination of magnetic fields, is presented as a verification of some of the results described by Messrs. A. R. Stevenson, Jr., and R. H. Park in a companion paper, “Graphical Determination of Magnetic Fields — Theoretical Considerations,” and to introduce new and convenient methods of determining the flux distributions in air spaces and in regions occupied by current carrying media. The particular case dealt with is the determination of the leakage flux about the field poles of an alternator at no load, both in the copper and in the surrounding air spaces.
