Keyboard graph navigation: press N for concepts or E for relations; use arrow keys, Home, and End to move; Enter selects; Shift plus Enter selects and centers; plus and minus zoom; zero fits; Escape clears the selection. Use the visible viewport buttons as alternatives to dragging, wheel, and pinch gestures.
Select a concept
Select any concept, construction junction, or annotated relation by pointer, touch, search, or keyboard.
Construction junctions are diamonds. They show where multiple structures must coexist on the same carrier and satisfy compatibility conditions.
Move selected concept
Single-pointer and keyboard alternatives to dragging. Each activation moves the selected concept one step.

electric current affects magnetism
Authored explanation
Ørsted’s result showed that electricity and magnetism were dynamically connected and launched the experimental program culminating in classical electromagnetism.
How to interpret this relation type
The source experiment, observation, anomaly, or problem materially motivated the development, revision, or acceptance of the target concept. Historical influence is not logical derivation; the edge detail states the documented role and avoids retrospective origin myths.

classical coherent-field limit
Authored explanation
Maxwell electrodynamics is recovered for suitable coherent states, weak quantum fluctuations, and classical sources; radiative quantum corrections are neglected.
How to interpret this relation type
The target is recovered from the source either in a stated mathematical or asymptotic limit, or through a quantitatively controlled approximation with identified small parameters or omitted terms. The edge label and detail must state which case applies and its regime of validity.

stationary-source regime
Authored explanation
Electrostatics neglects time dependence and induction/radiation effects for stationary or quasistatic configurations.

The experiments established electromagnetic radiation as a physical field phenomenon.
How to interpret this relation type
The source theory, law, entity, prediction, or structural claim is directly tested, supported, constrained, or established by the target experiment or observation. Experimental support is not final logical proof; the edge detail states exactly what was measured.
