What is recorded here?
Reported torsion experiments linking a change in magnetization to mechanical rotation, providing early experimental evidence for angular momentum associated with magnetism.
Source-linked catalogue note. A detailed explanatory guide has not yet been prepared for this entry.
Scientific scope
The record is the exact two-author 1915 experiment. Its classical orbital interpretation and reported gyromagnetic ratio had known limitations; the entry does not retroactively claim the modern electron-spin account or absorb later corrections.
