# Formula Bohr Magneton

## Bohr magneton

Unit
Magnitude of the magnetic dipole moment generated by an electron with orbital angular momentum quantum number $$l ~=~ 1$$ due to its orbital angular momentum.

## Electron mass

Unit
Electron mass is a physical constant and has the value: $$m_{\text e} ~=~ 9.109 \,\cdot\, 10^{-31} \, \text{kg}$$.

## Elementary charge

Unit
The elementary charge is a physical constant and is the smallest, freely existing electric charge in our universe. It has the exact value:$$e ~=~ 1.602 \, 176 \, 634 ~\cdot~ 10^{-19} \, \mathrm{C}$$

## Reduced Planck's constant

Unit
Reduced Planck's constant is a physical constant (of quantum mechanics) and has the value: $$\hbar ~=~ \frac{h}{2\pi} ~=~ 1.054 \,\cdot\, 10^{-34} \, \text{Js}$$.
