Opening Source Excerpt
Section titled “Opening Source Excerpt”D. C. COMMUTATING MACHINES 183 In Figs. 96, 97, 98, 99, curves are plotted corresponding to those in Figs. 92, 93, 94, and 95. As seen, the spread of mag- netic flux at the pole corners is greatly increased, but farther away from the field poles the magnetic distribution is not changed. 47. The magnetizing, or rather demagnetizing, effect of the load with shifted brushes is not changed. The distorting effect FIG. 96. — Flux distribution under a single pole. of the load is, however, very greatly decreased, to a small per- centage of its previous value, and the magnetic field under the field pole is very nearly uniform under load. The reason is: Even a very large increase of m.m.f. does not much increase the density, the ampere-turns being consumed by saturation of theSource-Located Theme Snippets

Modern Engineering Reading Prompts
Section titled “Modern Engineering Reading Prompts”- Magnetism: Track flux, reluctance, permeability, magnetizing force, and loss language against modern magnetic-circuit terminology.
- Field language: Read for whether field language is mechanical, geometrical, causal, descriptive, or simply a convenient engineering model.
Ether-Field Interpretive Boundary
Section titled “Ether-Field Interpretive Boundary”- Magnetism: Centrifugal/divergent magnetic-field readings are interpretive overlays, not automatic historical claims.
- Field language: Field-pressure or field-gradient interpretations can be explored here only after the explicit source passage and modern engineering translation are kept distinct.
Promotion Checklist
Section titled “Promotion Checklist”- Open the full source text and the scan or raw PDF.
- Verify the chapter boundary and surrounding context.
- Promote exact quotations only after checking the source image.
- Move mathematical candidates into canonical equation pages only after formula typography is corrected.
- Move diagram candidates into the diagram archive only after image extraction, crop verification, and manifest creation.
- Keep Steinmetz wording, modern translation, and ether-field interpretation in separate labeled layers.
