For an electron revolving in an atom, the angular momentum is quantized as proposed by Niels Bohr.
angular momentum = nh/2π
Where
n = orbit quantum number
h = Planck’s constant,
μ = n −e2me h2π
μ = −n eh4πme
The quantity that multiplies with n is a constant known as the Bohr Magneton μB,
μB = eh4πme = 9.27 × 10−27 J⁄T
The Bohr Magneton is used to express magnetic moments!
it is denoted by BM or μB
hope this helps!!
Verified answer
It is a physical constant and the natural unit for expressing for magnetic moment of an electron caused by either its orbital or spin angular momentum.
