Bohr Magneton experimental value

In summary, the Bohr Magneton experimental value is a physical constant that describes the magnetic moment of an electron in an atom. It was first discovered by Danish physicist Niels Bohr in 1913 and is significant in understanding the behavior of electrons in atoms. The value can be measured using various experimental techniques and has been revised over time as measurement techniques have improved. The current accepted value is considered to be accurate to within a few parts per million.

Dear ,

Thank you for reaching out to us for assistance. The current experimental value of the Bohr magneton is 9.2740100783(28)×10^-24 J/T, with an uncertainty of 28 parts per trillion. This value was determined by the National Institute of Standards and Technology (NIST) and is considered the most accurate and up-to-date value available.

You can find this information on the NIST website, specifically in the "Fundamental Physical Constants" section. You can also find it in various scientific databases and publications, such as the Particle Data Group's "Review of Particle Physics."

I hope this helps. Best of luck with your research.
