Design of a Halbach Magnet Array Based on Optimization Techniques

IEEE Transactions on Magnetics, 2008
We have designed a Halbach magnet array by using a numerical optimization method based on finite-element analysis. The magnetization direction of each element is defined as the design variable. The optimal magnet arrays composed of two and three linear magnet layers can then be investigated to increase the attractive, repulsive, and tangential magnetic

A passive shimming method for Halbach magnet based on magnetic sheet arrays

Journal of Magnetic Resonance, 2022
Halbach magnet has great potential in nuclear magnetic resonance device, where the field homogeneity requirement puts heavy demands on high efficiencypassive shimming (PS) technique. Conventional PS involves a tedious iteration process of the magnetic block/sheet number and positions optimization. In this paper, we propose a PS method based on magnetic

A concept for a magnetic particle imaging scanner with Halbach arrays

Physics in Medicine & Biology, 2020
Magnetic particle imaging (MPI) is a new medical imaging technique visualizing the concentration distribution of superparamagnetic nanoparticles used as tracer material. MPI is not yet in clinical routine, since one of the challenges is the upscaling of scanners.

A Halbach array magnetic spring

INTERMAG Asia 2005. Digests of the IEEE International Magnetics Conference, 2005., 2005
This paper summarises a research on a large load bearing magnetic spring concept, which has application to the development of a non-contact vibration isolation table. Also, the paper outlines the design of a magnetic spring with a single degree of instability that is suitable for bearing large loads.
