Abstract: (arXiv)
It is shown that general relativity coupled to nonlinear electrodynamics (NED) with the Lagrangian , having a correct weak field limit, leads to nontrivial static, spherically symmetric solutions with a globally regular metric if and only if the electric charge is zero and tends to a finite limit as . Properties and examples of such solutions, which include magnetic black holes and soliton-like objects (monopoles), are discussed. Magnetic solutions are compared with their electric counterparts. A duality between solutions of different theories specified in two alternative formulations of NED (called duality) is used as a tool for this comparison.- black hole: magnetic
