Bohr magneton

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:

where:

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
