Multiplying and dividing the R.H.S of equation (1) by m e,.The angular momentum of an electron due to its orbital motion is given by,.The orbital magnetic moment associated with the orbital current loop is given by,.The magnitude of circulating current is given by,.If the electron travels a distance 2πr in time T then, its orbital speed v = 2πr/T.Consider an electron of mass me and charge e revolving in a circular orbit of radius r around the positive nucleus in a clockwise direction, leading to an anticlockwise current. The quantity `"eh"/(4pi"m"_"e")` is a fundamental constant called the Bohr magneton, (5)Īccording to Bohr's second postulate of stationary orbits in his theory of hydrogen atom, the angular momentum of the electron in the nth stationary orbit is equal to n `"h"/(2pi)`, where h is the Planck constant and n is a positive integer. Where L 0 - m evr is the magnitude of the orbital angular momentum of the electron. Multiplying and dividing the right-hand side of the above expression by the electron mass m e, Therefore, the magnetic dipole moment associated with this electronic current loop has a magnitude Therefore, the orbital magnetic moment associated with this orbital current loop has a magnitude, Let r, v and T be the orbital radius, speed and period of motion of the electron. Send us feedback about these examples.In the Bohr model of a hydrogen atom, the electron of charge - e performs a uniform circular motion around the positively charged nucleus. These examples are programmatically compiled from various online sources to illustrate current usage of the word 'revolving.'
