Special Issue Information

Dear Colleagues,

Magnetic field sensing plays a pivotal role in varied applications, ranging from biomedical diagnostics and space science to industrial monitoring and quantum technologies. This Special Issue will present recent advances in magnetic field sensors and measurement techniques, covering both theoretical developments and practical implementations. Topics include sensor design, high-sensitivity and low-noise detection, zero- and ultra-low-field measurements, calibration methods, and novel applications in emerging interdisciplinary fields. Contributions addressing challenges in extreme environments or enabling next-generation technologies are particularly welcome.

Research on loss characteristics of magnetic components is a critical topic in power conversion technology. To address the significant discrepancies between existing core loss models and practical application requirements, this paper establishes a high-precision core loss evaluation model based on eXtreme Gradient Boosting. The model uses temperature, material, and excitation waveform as decision variables, with minimizing core loss as the objective. The study first evaluates the model through confusion matrices while conducting single-factor analyses of temperature, excitation waveform, and material using boxplots and investigating synergistic interactions between single factors. Subsequently, key metrics including coefficient of determination, mean squared error, and mean absolute error are employed for comprehensive regression assessment. Residual plots are utilized to examine the fit between predicted and actual values, demonstrating the model’s high accuracy, strong applicability, and practical relevance, thereby validating its superiority. Finally, the paper explores maximizing magnetic energy transmission by solving the optimization problem using simulated annealing algorithms to determine conditions that achieve both minimum core loss and maximum transmission efficiency, extending the research to multi-objective optimization.

Abstract
Vector magnetometer arrays are essential for ferromagnetic target detection and MGT measurement, but their performance is limited by proportional factor errors, triaxial non-orthogonality, soft/hard iron interference, and inconsistent array orientations.

Vector magnetometer arrays are essential for ferromagnetic target detection and MGT measurement, but their performance is limited by proportional factor errors, triaxial non-orthogonality, soft/hard iron interference, and inconsistent array orientations. Traditional rotation-based scalar calibration requires magnetic-free turntables or manual multi-orientation operations, introducing mechanical noise, orientation perturbations, and poor repeatability. This paper proposes an in situ rapid calibration method for MGT systems using triaxial Helmholtz coils. By generating three-dimensional magnetic field sequences of constant magnitude and random directions while keeping the sensors stationary, the method replaces conventional rotational excitation. A two-stage rapid calibration algorithm is developed to achieve individual sensor error modeling and array relative calibration. Experimental results show substantial improvements. The tensor invariant CT decreased from 6287.84 nT/m to 7.57 nT/m, with variance reduced from 1.46 × 106 to 13.47 nT2/m2; inter-sensor output differences were suppressed to 1–3 nT; and the magnetic field magnitude error dropped from ~940 nT to 3 × 10−4 nT, achieving a 5–6-order-of-magnitude enhancement. These results verify the method’s effectiveness in eliminating rotational errors, improving array consistency, and enabling high-precision in situ calibration with strong engineering value.
