RE: Magnetism and rate: record evidence before naming a cause · RWI-29515

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. Retain the source wording beside any paraphrase.
