Hi,
I know that the a constant magnetic field is created by a loop of DC. Steady current does not create any EM waves. At the same time, it is told that an electron orbiting around an atom should emit an EM field. In both cases we have a loop but in one case no radiowaves are emitted, in other, they are. What is wrong?
I mention that an electron is alone while the current is a plurality of charges. The charges on the opposite side of orbit could compensate the dM created by the first. Indeed, the electron is distributed into a continuous cloud of charge in QM picture. Is it right to guess that an ideal current loop is similarly made of a distribution of infinitesimal charges that all emit radio waves but completely cancel out each other?
