Dear Colleagues,

Magnetic devices have a long history of usage and play a crucial role in modern technology. Various advanced magnetic materials have been developed to improve their performance, such as soft magnetic composites, amorphous materials, nanocrystalline materials, grain-oriented SiFe, and 6.5% SiFe. Meanwhile, many new application-oriented design methods (such as novel topologies for electrical machines) and manufacturing methods (such as 3D printing) have been studied with the aim to make full use of these materials. Recently, digital twin technology has been used to visualize and monitor the operating conditions and evaluate the lifetime reliability of these devices. There are many challenges in developing efficient digital twin models, such as accurate lifetime models for magnetic materials and efficient reduced-order models.

This Special Issue aims to present a collection of scientific manuscripts covering the theoretical and practical aspects associated with digital twin models and their applications for magnetic devices. Contributions focusing on state-of-the-art and emerging developments in this field are welcome. Topics may include, but are not limited to, the following:

• Measurement and modeling of magnetic materials under different conditions;
• Multiphysics modeling and analysis;
• Reduced-order models for magnetic devices;
• Development of digital twin models for magnetic devices, including AI methods;
• Digital twins for the design, optimization, and manufacturing of magnetic devices;
• Digital twins for the condition monitoring, control, and reliability analysis of magnetic devices.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Magnetism is an international peer-reviewed open access quarterly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1000 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
