Axial Magnetostatics of a Ring Current in a Kerr Field

TL;DR

This paper models the electromagnetic fields of a ring current around a Kerr black hole and examines how these fields accelerate charged particles along the rotation axis, with implications for quasar astrophysics.

Contribution

It introduces a new model for the electromagnetic fields of a ring current in a Kerr spacetime and analyzes particle acceleration mechanisms.

Findings

Electromagnetic fields of a ring current in Kerr spacetime are characterized.

Charged particle acceleration along the rotation axis is demonstrated.

Implications for quasar astrophysics are discussed.

Abstract

The electromagnetic fields generated by a ring current around a Kerr black hole have been found. The acceleration of a charged particle by a force electric field along the rotation axis is investigated in the constructed model, as applied to the astrophysics of quasars.
