Charged Rotating Black Hole with an Anisotropic Matter Field: Solution of the Maxwell Field

Abstract

We study a rotating black hole with anisotropic matter and electromagnetic fields. We show that the electromagnetic field has the same form as the corresponding one in the Kerr-Newman geometry. The reason is thanks to the specific form of the metric function. We also mention energy extraction mechanisms from the black hole.
