PhD Studentship: Does the Earth magnetic field spin up the polar vortex in the outer core? Coventry University Group in United Kingdom

This PhD studentship at Coventry University Group investigates the intriguing question: Does the Earth's magnetic field spin up the polar vortex in the outer core? The project is situated within the Research Centre for Fluid and Complex Systems (FCS) and is funded by the Leverhulme Trust, which supports fundamental research of high significance and originality.

The research addresses one of the greatest mysteries in modern physics—the dynamo process responsible for generating planetary magnetic fields. Recent evidence suggests the existence of an intense polar vortex within the Earth's liquid core, specifically inside the Tangent Cylinder. The project aims to understand the origin and role of this vortex in the dynamo process, exploring the novel hypothesis that the magnetic field itself spins up large vortices in the polar region, potentially contributing to the Earth's dynamo.

The successful candidate will employ a combination of numerical simulations using advanced magnetohydrodynamic (MHD) models and experimental work with the unique Little Earth Experiment (LEE). LEE is the only device worldwide capable of reproducing and visualising convective flows in the Earth's liquid core, incorporating both rotational and magnetic effects. Experiments will be conducted in FCS's laboratory and at the high magnetic field laboratory in Grenoble, France, utilising some of the most powerful magnets available.

This studentship offers a unique opportunity to contribute to planetary science and develop expertise in geophysical, numerical, and experimental fluid dynamics. The candidate will benefit from comprehensive research training, including technical, personal, and professional skills, and will be part of Coventry University's Doctoral College and Centre for Research Capability and Development, which provides high-quality training and career development activities.

Applicants must hold at least a 2:1 first degree in a relevant discipline, with a minimum 60% mark in the project element or equivalent and a minimum 60% overall module average. The ability to engage in innovative research and complete the PhD within 3.5 years is essential. Applications require full supporting documentation, a covering letter, and a 500-word supporting statement outlining relevant expertise and interests.

For further information about the project, prospective candidates are encouraged to contact Professor Alban Potherat. The application deadline is 27 May 2026. Apply via the provided portal to join a world-leading research environment and contribute to advancing our understanding of planetary magnetic fields.
