Extremal black holes in strong magnetic fields: Near-horizon geometries and Meissner effect

Hejda, F., Bičák, J.

Abstract

For extremal black holes, one can construct simpler, limiting spacetimes that describe the
geometry near degenerate horizons. Since these spacetimes are known to have enhanced
symmetry, the limiting objects coincide for different solutions. We show that this occurs
for strongly magnetised Kerr-Newman solution, and how this is related to the Meissner
effect of expulsion of magnetic fields from extremal black holes.

Keywords

Black holes; strong magnetic fields; near-horizon limit; Meissner effect.
