...evidence came in when the strength of the sun's magnetic field was measured. It turned out to be closely proportionate to the earth's, allowing for the sun's greater mass and slower turning. But two observations are not enough to base a general law on; they might be mere coincidence...
...Last year some new evidence turned up. Dr. H. W. Babcock of Mt. Wilson Observatory, Calif, performed the unlikely feat of measuring (by spectrum analysis) the magnetic field of the star called 78 Virginis. When Professor Blackett heard about it, he grabbed pencil & paper. The star's size, mass and speed of revolution could be estimated fairly accurately. Nothing more was needed. The magnetic field of remote 78 Virginis just about proved what theorizing had already predicted: it was closely proportionate to the magnetic fields of the earth...
