A genuine progress would be to attribute to the electron a dual property of electric charge and magnetic dipole. If one looks at the history of the discovery of the spin and the magnetic dipole of the electron, then the following development would also be possible:
- The electron is (in addition to its electric charge) a magnetic dipole.
- When moving in a magnetic field, the external magnetic field influences the orientation of the magnetic dipole of the electron. The emission of EM radiation that occurs deflects the electron firstly and secondly periodically disturbs the orientation of the electrons magnetic dipole to the external magnetic field. In the process, the electron is directed onto a spiral path and comes to a standstill in its centre after exhausting all of its kinetic energy.
Thus the analogy of the gyroscopic behaviour of a rotating mass and the deflection of the electron in the magnetic field is invalid.
The electron does not need spin to explain its deflection behaviour.
