# A tale of two dyons

## TL;DR

This paper introduces a new family of Einstein-Maxwell solutions describing two co-rotating black holes with specific charge and magnetic properties, connected by a string-like structure, expanding understanding of complex black hole configurations.

## Contribution

It presents a novel one-parameter family of solutions modeling two extreme co-rotating black holes with unique charge distributions and a connecting string, with minimal singularities.

## Key findings

- Describes a family of solutions with mass, angular momentum, dipole magnetic, and quadrupole electric moments.
- Models two extreme co-rotating black holes with specific charge configurations.
- Includes analysis of the solution's structure and physical interpretation.

## Abstract

We present a one-parameter family of stationary, asymptotically flat solutions of the Einstein-Maxwell equations with only a mild singularity, which are endowed with mass, angular momentum, a dipole magnetic moment and a quadrupole electric moment. We briefly analyze the structure of this solution, which we interpret as a system of two extreme co-rotating black holes with equal masses and electric charges, and opposite magnetic and gravimagnetic charges, held apart by an electrically charged, magnetized string which also acts as a Dirac-Misner string.
