Non‐Linear Electrodynamics in Blandford–Znajek Energy Extraction

Non-linear electrodynamics (NLED) is a generalization of Maxwell's for strong fields. It has significant implications the study black holes and cosmology been extensively studied in literature, extending from quantum to cosmological contexts. In this work, two new ways investigate these non-linear theories are investigated. First, Blandford-Znajek mechanism analyzed light promising theoretical context, providing general form extracted power up second order hole spin parameter a. found that, depending on NLED model, emitted can be extremely increased or decreased, that magnetic field lines around seem become vertical quickly. Considering only separated solutions, it no monopole solutions exist could have interesting astrophysical consequences (not considered here). Last but not least, attempted confine parameters by inducing amplification primordial fields (“seeds”), thus admitting already during early stages Universe. However, latter approach proves useful research certain models. These (analytical) results emphasize behavior electromagnetic phenomena strongly depends physical context power-law model seems any chance compete with Maxwell.
