| contents | This paper examines regular black holes, in particular the Bardeen spacetime where singularities are replaced by non-singular cores. It explores the energy extraction through the charged Penrose process and shows that magnetic charge evaporation can drive a regular black hole towards a singularity. Two evaporation models are proposed, dealing with charge loss and combined charge evaporation with mass accretion, providing insights into the evolution and stability of regular black holes. |
