What this page is

This is a public Results-lane surface for a noteworthy Physics Registry item. It is generated from the Corpus Registry triage catalogue and keeps the generic Result catalogue unchanged.

Registry evidence

  • Registry item: IV.P48
  • Type: proposition
  • Scope: tau-effective
  • Lean status: formalized
  • Book / part / chapter: Book IV · Part 4 · Chapter 28

Result summary

The magnetic component F_B = q v x B is perpendicular to velocity, so F_B dot v = 0: magnetic field changes direction but not speed.

Reading role

Use as Registry evidence for an existing Results surface.

Claim boundary

This page reports a Registry-backed internal result surface. It is not an external validation claim, a scientific consensus claim, or independent acceptance.

Curation rationale

  • physics-facing terms: magnetic
  • candidate is better handled as evidence for an inferred existing public surface

Review notes

  • No additional review notes recorded.
