What is value of Bohr Megneton??
Answers
Explanation:
Magnetic moment of an electron is caused by its orbital or spin orbital momentum. The physical constant which represent this magnetic moment which is caused by either its orbital or spin angular momentum is called Bohr magneton. It is represented by the symbol m B .
In SI units it is defined by the equation
us= eh/2me
In CGS unit it is defined by the equation
us = eh/2mce
Here e represents the elementary charge, represents reduced Planck's constant, me is the reduced mass of electron, and c represents speed of light.
The magnetic moment of electron is approximately equal to one Bohr magneton and the value of one Bohr magneton is equal to 9.274 × 10–24J/T.
In order to derive the equation for Bohr magneton we consider an electron which moves around a circular having radius r with a velocity v.The time period for this orbit is given by the equation

Answer:
Explanation:
In atomic physics, the Bohr magneton (symbol μB) is a physical constant and the natural unit for expressing the magnetic moment of an electron caused by either its orbital or spin angular momentum. The Bohr magneton, named for the 20th-century Danish physicist Niels Bohr, is equal to about 9.274 × 10−21 erg per gauss per particle.
