The Bohr magneton (symbol ), sometimes also called Landé factor, is named after the physicist Niels Bohr.
It is a physical constant of magnetic moment, defined by:
- is the elementary charge,
- is the Dirac's constant,
- is the electron rest mass
In the SI system of units
it's value is approximately:
- = 9.274 008 99(37) × 10-24 J·T-1
