<p class="xmsonormal"><span style="font-size:12.0pt;font-family:"Aptos",sans-serif;color:black">Magnetic fields have been observed in galaxies, galaxy clusters, and even in the intergalactic medium. While astrophysical mechanisms can account for the magnetic
fields in galaxies and galaxy clusters, they may not fully explain the presence of magnetic fields in the intergalactic medium. In this talk, I will discuss the generation of these large-scale magnetic fields in the early universe, potentially arising during
the inflationary era. I will present my work, which addresses the challenges associated with generating these fields during inflation. Furthermore, I will discuss our recent work exploring the possibility of magnetic field generation In the Spectator Chromo-Natural
Inflation (SCNI) model. In this model, inflationary magnetogenesis is realized by identifying the non-Abelian sector of SCNI with the SU(2)_L sector of the Standard Model, providing a novel mechanism for the emergence of primordial magnetic fields during inflation.<o:p></o:p></span></p>
