Opening Source Excerpt
Section titled “Opening Source Excerpt”IX. Magnetic Characteristic or Saturation Curve 20. The dependence of the generated e.m.f., or terminal voltage at open circuit, upon the field excitation is called the magnetic characteristic, or saturation curve, of the synchronous 1000 2000 3000 4000 5000 FIG. 69. — Synchronous generator magnetic 7000 characteristics. machine. It has the same general shape as the curve of mag- netic flux density, consisting of a straight part below saturation, a bend or knee, and a saturated part beyond the knee. Gener- ally the change from the unsaturated to the over-saturated por- tion of the curve is more gradual; thus the knee is less pronounced in the magnetic characteristic of the synchronous machines, since the different parts of the magnetic circuit approach saturation successively.

Modern Engineering Reading Prompts
Section titled “Modern Engineering Reading Prompts”- Field language: Read for whether field language is mechanical, geometrical, causal, descriptive, or simply a convenient engineering model.
- Magnetism: Track flux, reluctance, permeability, magnetizing force, and loss language against modern magnetic-circuit terminology.
- Impedance / reactance: Translate historical opposition terms into modern impedance, admittance, conductance, susceptance, and complex-plane notation.
Ether-Field Interpretive Boundary
Section titled “Ether-Field Interpretive Boundary”- 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.
- Magnetism: Centrifugal/divergent magnetic-field readings are interpretive overlays, not automatic historical claims.
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.
