Einstein's Magnetic Effect Is Measured on Microscale
    
  In NIST's Einstein-de Haas experiment, the movements of a cantilever were measured with an optical-fiber laser interferometer. The optical fiber is 125 micrometers in diameter, and the end is positioned less than 10 micrometers from the cantilever surface.
