Foundations · builds on
Electromagnetic inductiondepends onMagnetic fieldEstablished
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.

dynamic microphone depends on electromagnetic induction.
Mechanism: Its coil moving in a magnetic field induces the signal voltage.

Electromagnetic induction causes electric current.
Mechanism: A changing magnetic field induces a voltage and current in a nearby conductor — the basis of generators.

Structural role & consequence
Interpreted from the current atlas graph — what the connections mean, not just how many there are.
25% of its relationships cross field boundaries, reaching 3 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.
Directly enables 1 concept; following enables/causes relations, 2 concepts are downstream across 3 disciplines.
structural · Follows only enables/causes dependency edges — not general relatedness.
Currently dark in the atlas: 4 of 4 of its relations lack claim-level evidence.
atlas representation · Describes the current Thinking OS representation, not the state of the world.
Builds on 1 foundation (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
Conditions
- Its dependency reading rests on 1 foundation relation. structural
- Read structurally — most of its relationships carry no external evidence yet, so claims here are graph-derived. structural

What this concept builds on (left) and what it makes possible (right) — derived from dependency and causal relations.
What builds on this
1 concept build on this directly, 1 in total, across 2 disciplines.
Structural downstream reach along dependency edges — not a claim of historical necessity.
Seen through each discipline
How this concept sits in each of its fields — derived from its real connections in the graph, not asserted.
Through this lens it connects to Electric current, Magnetic field and Faraday's law of induction.
