Interaction between an electric charge and a magnetic dipole of any kind (permanent, para- or dia- magnetic or superconducting)

TL;DR

This paper generalizes the analysis of the interaction between a point charge and various types of magnetic dipoles, including rigid, paramagnetic, diamagnetic, and superconducting, focusing on force, momentum, and energy considerations.

Contribution

It extends the classical interaction analysis to encompass all magnetic dipole behaviors, not just rigid ferromagnetic ones.

Findings

Unified framework for charge-dipole interaction across different magnetic behaviors

Analysis of force, momentum, and energy for various dipole types

Inclusion of superconducting diamagnetism in the interaction model

Abstract

The interaction between point charge and magnetic dipole is usually considered only for the case of a rigid ferromagnetic dipole (constant-current): here the analysis of force, momentum and energy (including the energy provided by the internal current generator) is generalised to any magnetic dipole behaviour: rigid, paramagnetic, diamagnetic or superconducting (perfectly diamagnetic).
