Case 27 — Magnetism and rate: record evidence before naming a cause

Correction note for “Magnetism and rate: record evidence before naming a cause”: retain the wording beginning “Record the change and the circumstances without treating…” in the record. If later material changes it, add the date, the changed wording and the source for that change; do not invent a completed correction here. Keep the stated question separate from any broader claim.
