This approach enables the inclusion of effects such as mechanical stress, magnetostriction, material anisotropy, and crystallographic texture. By integrating the anhysteretic model into the EB framework, it becomes possible to account for dissipative effects (in our case, domain wall pinning) while utilizing detailed material information. To solve the EB model in conjunction with the SMSM, two approaches are pursued: a numerical optimization of a free energy functional and an explicit approximate variant, known as the vector play model (VPM). Both methods are compared in terms of computational performance, and the differences in results are demonstrated through the simulation of the cross section of an electric machine. Furthermore, the local as well as global behavior is investigated. It is shown that in an electrical machine configuration, the VPM provides a very satisfactory approximation to both local and global responses, together with a reduced computation time compared to the EB model. In the provided application case, it is shown that a shrink-fitting operation can lead to a 30% increase in the overall hysteresis losses.","PeriodicalId":13405,"journal":{"name":"IEEE Transactions on Magnetics","volume":"61 8","pages":"1-14"},"PeriodicalIF":2.1,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11062564","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144716345","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, traditional algorithms for DW velocity extraction often suffer from inaccuracies, limiting the precise correlation between microscopic domain dynamics and macroscopic magnetic Barkhausen noise (MBN). In this study, we quantitatively compare the accuracy of multiple optical flow algorithms in DW velocity extraction. First, we establish rigorous error metrics to evaluate optical flow performance. We then optimize the parameters of three optical flow algorithms—Horn–Schunck (H–S), Brox, and Classic + NL—and demonstrate that Classic + NL outperforms the others in both standard test images and experimental domain motion images. Furthermore, we validate the Classic + NL algorithm’s reliability through correlation analysis between the DW velocity and MBN envelope. This framework provides a robust foundation for linking microscopic DW motion with macroscopic MBN responses, advancing the precision of domain dynamics characterization.","PeriodicalId":13405,"journal":{"name":"IEEE Transactions on Magnetics","volume":"61 8","pages":"1-11"},"PeriodicalIF":2.1,"publicationDate":"2025-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144716197","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Measurement of the magnetic moment is important for target detection, classification, and localization. In this article, we propose a method of calculating the magnetic moment using magnetic gradient tensor (MGT) eigenvalues. We first derived equations for inverting the magnetic moment from MGT eigenvalues and eigenvectors. We then conducted simulations for different conditions of the target pose, target distance, and relative position, and obtained the applicable conditions of the method. We finally conducted experiments using a full MGT sensor developed by our team. The experimental results were consistent with the simulation results. Under the applicable conditions, the calculation error of the magnetic moment magnitude was <inline-formula> <tex-math>$le 0.5$ </tex-math></inline-formula> Am2 and the direction error was <inline-formula> <tex-math>$le 5^{circ }$ </tex-math></inline-formula>. However, the method places restrictions on the pose of the target relative to the MGT sensor, which introduces obvious limitations. Therefore, we created a rotation-averaged error correction algorithm that makes the method applicable to any target pose. The method is expected to be applied to the rough calibration of target magnetic moments and may be helpful to the identification of small magnetic targets.","PeriodicalId":13405,"journal":{"name":"IEEE Transactions on Magnetics","volume":"61 8","pages":"1-12"},"PeriodicalIF":2.1,"publicationDate":"2025-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144716241","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
