On the Magnetic Moment of Electron and its Significance for the Standard Model

By Amal Pushp, Affiliate Physicist at the Resonance Science Foundation 

The magnetic moment of an electron is essentially an inherent property that emerges from the particle’s charge and spin. Physicists know that elementary particles like electrons display two kinds of angular momentum: orbital and spin which collectively is known as the spin-orbit coupling. This collective dynamical behavior further gives rise to the magnetic dipole moment or simply the magnetic moment. In fact, the magnetic dipole moment can also appear separately as spin and orbital magnetic dipole moment.  

In general, the magnetic moment can be described as a representation of the strength of any magnetic source. Consider a classical representation of an electron. Due to the charge distribution of the electron, which is essentially rotating, there is a creation of a magnetic dipole or in other words, the electron behaves as a microscopic bar magnet which...
