Neutron stars serve as unique natural laboratories for exploring physics under extreme conditions. These dense stellar remnants exhibit exceptionally strong magnetic fields, featuring complex origins and internal structures that continue to challenge our understanding, despite decades of theoretical and observational efforts. Understanding the internal magnetic field topology and its equilibrium configurations is crucial for determining the structure and long-term stability of neutron stars. In this talk, I will discuss how general relativistic magnetohydrodynamic (GRMHD) simulations are employed to explore key questions: Can stable magnetic equilibria exist inside neutron stars? What physical processes govern the approach to equilibrium? And how does turbulence affect the evolution of the magnetic field?
