COMMUTATING MACHINES 179 acting upon the air gap between armature and field pole, la = length of air gap, from iron to iron, the density under the magnet pole, that is, in the range BC of Fig. 90, is At a point having the distance lx from the end of the field pole on the armature surface, the distance from the next field pole is ld = Vk2 + lx2, and the density thus, approximately, B C FIG. 92. — Distribution of mganetic flux under a single pole. Herefrom the distribution of magnetic flux is calculated and plotted in Fig. 92, for a single pole BC, along the armature sur- face A, for the length of air gap la = 1, and such a m.m.f. as to L FIG. 93. — Distribution ofSource-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.
