A one-day event on the extreme edges of magnetics – the biggest, fastest, smallest, strongest. If you’re interested in magnets and magnetics, there’ll be a technical talk for you.

The virtual event will include presentations and networking opportunities amongst a global audience. Talks will range from magnetospheres for planetary habitats, to micro-scale Nd magnets, including extremely challenging measurements, designing high speed motors, and more.

Join us to find out what’s happening at the cutting edge, and maybe find the germ of an idea for the problem you’re struggling with.

How to build a magnetic field around Mars for terraforming
by Dr Ruth Bamford of Science and Technology Facilities Council (STFC), Rutherford Appleton Laboratory

If humanity is ever to consider substantial, long-term colonization of Mars, the resources needed are going to be extensive. For a long-term human presence on Mars to be established, serious thought would need to be given to terraforming the planet. One major requirement for such terraforming is having the protection of a planetary magnetic field - which Mars currently does not have. The Earth’s magnetosphere helps protect the planet from the potential sterilizing effects of cosmic rays and also helps retain the atmosphere, which would otherwise by stripped by large solar storms as they pass over the planet. Here we explore the practical and engineering challenges that affect the feasibility of creating an artificial magnetic field capable of encompassing a planet. This includes the concerns that define the design, where to locate the magnetic field generator and possible construction strategies. The optimum solution proposed is novel, although inspired by natural situations at Io-Jupier and fusion plasma techniques.

From µs high intensity magnetic field pulses to µm high performance magnets
by Nora Dempsey of Institut NEEL, CNRS

Hard magnetic thin and thick films can serve as model systems to study high performance hard magnetic materials, and have potential applications in magnetic nano/micro devices. In this talk I will firstly speak about µs pulsed magnetic field systems producing field pulses of intensity up to 10 T, which have been developed for the high throughput characterization of compositionally graded hard magnetic films. I will then speak about the micro-patterning of hard magnetic films to produce micro-magnets characterized by field gradients of the order of 106 T/m. I will finish up by presenting examples of applications of these high performance micro-magnets in bio-medical studies and electro-mechanical actuators.

Highly Perturbed Magnetic Systems Stimulated by Ultrafast Laser Pulses
by Rob Hicken of Department of Physics and Astronomy, University of Exeter

The equilibrium state of a magnetic material is defined by the occupation of its electronic states and is described by an energy distribution associated with a temperature. Exposure to an intense ultrafast laser pulse allows the states of specific electrons to be modified on timescales that are short compared to their relaxation times. The resulting non-equilibrium state of the material exists on timescales of ~10-13 s before relaxing to a state with an electron temperature that may be elevated by ~103 K. I will discuss how these extreme states might mediate ultrafast magnetization reversal for use in future ultrafast ultra-dense data storage technology.

Benefits and differentiation of rotor reinforcements made of (carbon/glass/aramid…) fiber composites
by Julia Moegel & Simon Burkhart of CirComp GmbH

Demanding rotor applications require a coordinated and targeted selection of rotor reinforcement materials and processes to achieve maximum results. Requirements that need to be taken into account are forces and temperature in use, but also the conditions of the assembly process. Subject of the presentation will be how design criteria can determine quality, effort and cost of the reinforcement.

The ZEPTO project: Energy saving magnets for the next generation of particle accelerators
by Alex Bainbridge of STFC Daresbury Laboratory

The increasing power demands of new particle accelerator technology is problematic from both an environmental and financial perspective. The ZEPTO (zero power tuneable optics) project aims to solve some of these issues by replacing conventional electromagnets in accelerators with energy saving permanent magnets. ZEPTO technology retains field tuneability without affecting field quality by moving the permanent magnet relative to fixed steel structures. We present an overview of ZEPTO technology and discuss the challenges involved, including detailed finite element modelling and complex management of large and variable magnetic forces.
