Dependencies

What this concept builds on and what it makes possible — derived from the atlas’s dependency, causal and structural relations, not from every related edge.

Foundations · builds on

Electric currentcausesMagnetic fieldEstablished

Open Electric current →

electric current causes magnetic field.

Mechanism: A moving electric charge — a current — produces a magnetic field around it.

Sources:

Open Magnetism →

magnetism causes magnetic field.

Mechanism: Magnetism produces a magnetic field: moving charges and aligned atomic spins create the field that pushes on other magnets and currents.

Electromagnetic inductiondepends onMagnetic fieldEstablished

Open Electromagnetic induction →

Electromagnetic induction depends on magnetic field.

Mechanism: Induction depends on a changing magnetic field: when the field through a coil changes, it drives a voltage that makes current flow.

Sources:
Electromagnetic radiationemerges fromMagnetic fieldEstablished

Open Electromagnetic radiation →

Electromagnetic radiation emerges from magnetic field.

Mechanism: Electromagnetic radiation emerges from changing fields: a shifting electric field makes a magnetic one and vice versa, so the pair travels as a self-sustaining wave.

Sources:
Magnetic resonance imagingdepends onMagnetic fieldEstablished

Open Magnetic resonance imaging →

Magnetic resonance imaging depends on magnetic-field.

Mechanism: MRI aligns hydrogen nuclei in a strong magnetic field to generate its images.

Sunspotdepends onMagnetic fieldEstablished

Open Sunspot →

sunspot depends on magnetic field.

Mechanism: Sunspots are cooler patches where the Sun's intense magnetic field suppresses convection.

Structural role & consequence

Interpreted from the current atlas graph — what the connections mean, not just how many there are.

  • Removing this node lengthens the structural route between Magnetic resonance imaging and Sunspot from 2 to 12 steps (they stay connected — alternative routes exist).

    structural · Structural removal simulation — not a historical or causal counterfactual.

  • 33% of its relationships cross field boundaries, reaching 5 other disciplines — unusual in a discipline where most concepts stay within their field.

    structural · Structural graph analysis — not a claim of importance, causation or history.

  • Currently dark in the atlas: no key date stored · 6 of 6 of its relations lack claim-level evidence.

    atlas representation · Describes the current Thinking OS representation, not the state of the world.

  • Builds on 2 foundations (requires / depends-on / derived-from / emerges-from).

Strengths & constraints

Constraints

  • Evidence coverage currently thin in the atlas — few of its relationships carry claim-level evidence. atlas representation
  • No dated history stored — the atlas records no key date for this concept. atlas representation

Conditions

  • Its dependency reading rests on 2 foundation relations. structural
  • Read structurally — most of its relationships carry no external evidence yet, so claims here are graph-derived. structural

Concepts

The scientific picture
  • Connects 6 other ideas across 2 disciplines.
  • A cross-disciplinary bridge — its connections reach into 5 other fields.
  • Most of its connections are of the “Cause & effect” kind.

Derived from the graph’s real structure — observations, not a score.
