hi,i know these, my mean that the magnitude magnetic field B formule that i find here my question is that we consider Coulomb force in Bohr's theory but don't consider the electromagnetic field? An accelerated charge has magnetic field according Maxwell's theory.
Why don't we consider the electromagnetic field in the equations of Bohr's theory of atoms?
The Bohr model is a phenomenological model in analogy to the planetary model. The electric field is a part of the electro magnetic field. Qualitatively, a negative charge orbiting a positive charge is expected to emit electromagnetic radiation , and in the classical model it is expected they will fall on each other. The data Bohr fitted, the Lyman and Balmer series, showed a discrete spectrum for hydrogen, not a continuum.
In such a model the stability of the orbits has to be postulated, that the electrons could only radiate in transition between fixed orbits in discrete steps corresponding to the observations.
So in a sense the model goes beyond classical electromagnetism, and it needed the development of quantum mechanics and quantum electrodynamics for mathematical accuracy in modelling atoms.
