Generating and using high magnetic fields
by Amalia Patanè of University of Nottingham

This lecture reviews recent advances in the generation and use of high magnetic fields at the European Magnetic Field Laboratory (EMFL). The EMFL unites, coordinates and reinforces all existing European large-scale high magnetic field research infrastructures in a single body. It includes the Laboratoire National des Champs Magnétiques Intenses (LNCMI) with sites in Grenoble and Toulouse, the High Field Magnet Laboratory (HFML - Nijmegen) and the Hochfeld-Magnetlabor (HLD - Dresden) providing access to the highest continuous and pulsed magnetic fields in Europe. The HFML-Nijmegen and the LNCMI-Grenoble are committed to generate the highest continuous magnetic fields, currently up to 38 T. The HLD-Dresden and the LNCMI-Toulouse focus on non-destructive pulsed fields, currently up to 100 T, and semi-destructive fields up to 200 T. Besides the continuous improvement of the magnetic field strength, the realization and accessibility of top-class experimental infrastructure is of critical importance for science and technology. Existing experimental setups are continuously improved and experimental techniques, so far not often used in high fields, are developed, such as scanning-probe microscopy, high pressure and micro-calorimetry measurements.

The ZEPTO project: tuneable permanent magnets
by Ben Shepherd of STFC Daresbury Laboratory

Particle accelerators use huge amounts of energy to accelerate and guide beams of charged particles. Much of that energy goes into resistive magnets. Permanent magnet based devices offer an alternative, but at the cost of reduced adjustability. STFC’s Zero-Power Tuneable Optics (ZEPTO) project aims to give the best of both worlds – a focusing quadrupole magnet with a large adjustment range but using no energy in normal operation.

IMPACT: Working with industries on renewable energy and electrification
by Zi-Qiang Zhu of University of Sheffield

This presentation will focus on Sheffield’s industrial co-operation on renewable energy and electrification to illustrate the development of new research concepts, novel enabling technologies, and their impact on successful commercial applications, with particular reference to permanent magnet machines and systems. His own worked examples will be used for building the bridges among the government and industrial funding, fundamental and applied research, as well as R&D and commercial exploitation.

Magnets, Fusion and Beyond
by Stuart Clark of

Having recently been working with The Fusion Cluster in Culham, the crucial role of magnets in the commercial realisation of that technology has been brought home to me. In this talk, I would like to explain my journey into the world of fusion magnetics, my perceptions of the breakthrough in high temperature superconducting magnets and why we have a unique opportunity to lift the public perception of magnetics across the board.

The Use of Hydrogen In the NdFeB Magnets Industry
by Dr Oliver Brooks of Magnets Group, University of Birmingham

Hydrogen has played a pivotal role in the manufacturing of rare earth magnets since their inception. This presentation provides an overview of the historical significance of hydrogen in the production of sintered rare earth magnets. Additionally, it explores alternative production routes, examines its application in recycling processes, and delves into its utilisation in a potential cutting-edge production technique currently being researched at the University of Birmingham. The presentation aims to offer an understanding of the evolving role of hydrogen in various facets of rare earth magnet production, showcasing its enduring importance and potential innovations in the field.

Developing a supply chain for Rare Earth Magnets
by William Izod of Pensana Plc

The energy transition is driven by advanced materials and in particular the high-performance magnets essential to the Automotive industry for Electric drive units (EDU) and the Offshore wind nacelles. The supply chains supporting these materials are complex and commonly involve supply chains monopolised by China. Pensana is looking to establish an independent sustainable supply chain for these materials with processing in the UK delivering the magnet metal critical for the net-zero future. Utilising green energy at both the mine site and processing facilities it will deliver the lowest embedded carbon rare earth products in the industry.

Rare Earth Metallurgy and Evolution of Demand
by Dave Kennedy of Hypromag

A description of the methods of manufacturing rare earth metals and alloys and the changing demands of commercial exploitation since 1980. Extending into consideration of the separation methods for rare earth elements and the problems of imbalance in demand compared with natural occurrence. With few exceptions the rare earths occur naturally as a mixture of many elements, up to 16 rare earth metals, each with very similar chemical properties. Over the last 40 years the demands in application have changed and today the commercial driver for the entire industry are the elements in demand for permanent magnets. This is the “Balance Problem” for the fundamental resources of rare earths in mining and processing. Recycling of rare earth permanent magnets has been non-existent. Historically any rare earth content was lost to slags in the remelting of alloys to recover other metals. The new methods of recovering alloys for re-use are overcoming the fundamental challenges of oxidation potential and the impact of contamination on recycled magnets.
