# Defying inertia: how rotating superconductors generate magnetic fields

## TL;DR

This paper explains how rotating superconductors generate magnetic fields through a process that challenges conventional theory, favoring the hole superconductivity theory which aligns with experimental results.

## Contribution

It demonstrates that the hole superconductivity theory better explains magnetic field generation in rotating superconductors than conventional theory.

## Key findings

- Experimental observations match hole superconductivity predictions.
- Electrons change speed depending on geometry during cooling.
- Conventional theory does not account for these magnetic effects.

## Abstract

I discuss the process of magnetic field generation in rotating superconductors in simply connected and multiply connected geometries. In cooling a normal metal into the superconducting state while it is rotating, electrons slow down or speed up depending on the geometry and their location in the sample, apparently defying inertia. I argue that the conventional theory of superconductivity does not explain these processes. Instead, the theory of hole superconductivity does. Its predictions agree with experimental observations of Hendricks, King and Rohrschach for solid and hollow cylinders.
