Magnetism

Magnetism is the class of physical attributes that occur through a magnetic field, which allows objects to attract or repel each other.

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.

Structural role & consequence

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

  • Directly enables 1 concept; following enables/causes relations, 1 concept is downstream across 2 disciplines.

    structural · Follows only enables/causes dependency edges — not general relatedness.

  • Currently dark in the atlas: 1 of 1 of its relations lack claim-level evidence.

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

  • Structural neighbourhood: 1 → 6 → 28 concepts reachable within 3 hops.

    structural · Structural reach — being reachable is not the same as being understood.

  • All 1 of its relationships stay within its own discipline — a field-specific concept in the current atlas.

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

Strengths & constraints

Constraints

  • Evidence coverage currently thin in the atlas — few of its relationships carry claim-level evidence. atlas representation

Conditions

  • Read structurally — most of its relationships carry no external evidence yet, so claims here are graph-derived. structural

The scientific picture
  • Connects 1 other ideas across 2 disciplines.
  • Most of its connections are of the “Cause & effect” kind.

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