Question

What is BM in magnetic moment?

Answer 1

1. The magnetic moment can be defined as the magnetic field produced by a magnet or other object, along with its direction and strength.
2. BM refers to Bohr magnetron and it is the unit of the magnetic moment.
3. $$\begin{gathered} {\mu }_B=\frac{eh}{4{\mathrm{\pi m}}_{\mathrm{e}}} \\ {\mathrm{m}}_{\mathrm{e}}\mathrm{is}\mathrm{mass}\mathrm{of}\mathrm{electron},\mathrm{e}=\mathrm{charge}\mathrm{of}\mathrm{particle} \end{gathered}$$ ${\mu }_B$ represents the Bohr magneton, $g$ represents constant, $s$ represents electron spin, $h$represents Planck's constant.
4. $BM$ is the unit of the magnetic moment.
5. Every electron has a Bohr magneton amount of ${\mu }_B=9.27\times {10}^{-24}J{T}^{-1}$ which is parallel to the spins.
