Bohr magneton
From Wikipedia, the free encyclopedia
In atomic physics, the Bohr magneton (symbol μB) is named after the physicist Niels Bohr. It is a physical constant of magnetic moment, defined in S.I. units by:
and in Gaussian centimeter-gram-second units by:
where:
- e is the elementary charge,
is the reduced Planck's constant,- me is the electron rest mass
- c is the speed of light.
In the SI system of units its value is:
The Bohr magneton is the natural unit for expressing the electron magnetic dipole moment.
The Bohr magneton was first calculated by Romanian physicist Stefan Procopiu and is also known as the Bohr-Procopiu Magneton.
