“…The position of the MNPs able to respond to the field of excitation will be determined by this coil. [79,80] Following that, the MNPs will be excited by a magnetic field created by the excitation coil or driving coil. To activate the MNPs, the excitation coil should create a strong and uniform magnetic field.…”

This article presents a comprehensive review of current Magnetic Imaging Techniques (MIT), specifically Magnetic Particle Imaging (MPI) and Magnetic Resonance Imaging (MRI) methods as well as their impacts and potential in biomedical applications.The paper particularly focuses on several perspectives of MPI and MRI techniques including technical considerations, advantages, limitations, applications, future trends. Surprisingly, there are not many review articles that focused on MPI and MRI. This review will give a complete overview of present technology, perspectives, and potential future developments for MPI and MRI. MIT has become an essential and integral part of medical diagnosis in many large medical clinics and hospitals. This area is rapidly developing and evolving to meet the huge demands in medical diagnosis and prevention. MPI and MRI are promising technologies that provide reliable and effective diagnosis for many diseases including cancer. MIT uses non-invasive scanning to obtain a detailed image of the body's tissues or organs without the necessity for surgery. These techniques allow us to detect symptoms of serious diseases at an early stage. Early detection also gives patients the chance to get the right care before their illnesses advance to a late, incurable stage, potentially saving many lives.

“…Subsequently, various optimization methods have been suggested. These methods are based on the finite element method (FEM) [25], modification of the coil model (addition of a magnet for shielding) [26,27], or coil analytic models [28,29]. The investigation of the optimal coil parameters through FEM simulation shows a higher execution time and the requirement for specific modern tools that are not always available.…”

Inductive wireless power transfer is a promising technology for powering smart wearable devices. The spiral coil shape is widely used in wireless power transfer applications. Nevertheless, during the coil design process, there are many challenges to overcome considering all the design constraints. The most important is to determine the optimal coil parameters (internal radius, external radius, spacing, wire width, and conductive wire) with the aim of obtaining the highest coil quality factor. Coil modeling is very important for the wireless power transfer system’s efficiency. Indeed, it is challenging because it requires a high computational effort and has convergence problems. In this paper, we propose a new approach for the approximation of spiral coils through concentric circular turns to reduce the computational effort. The mathematical model determines the optimal coil parameters to obtain the highest coil quality factor. We have chosen the smart textile as an application. The system operates at a frequency of 100 Khz considering the Qi guidelines. To validate this approach, we compared the approximated circular coil model with the spiral coil model through a finite element method simulation using the COMSOL software. The obtained results show that the proposed approximation reduces the complexity of the coil design process and performs well compared to the model corresponding to the spiral shape, without significantly modifying the coil inductance. For a wire width smaller than 1 mm, the total deviation is around 4% in terms of the coil quality factor in a predetermined domain of its parameters.

This work proposes a novel method for in situ measurement of the non‐orthogonal angles of magnetic field coils based on single‐beam magnetic resonance. The orthogonality of magnetic field coils is crucial for ensuring the accuracy of atomic magnetometers. The theoretical principles are derived to establish a measurement method for the non‐orthogonal angles. The proposed method requires only one single beam of light to perform in situ measurements of non‐orthogonal angles in the YZ and XZ directions. The experimental results demonstrate that the angle between the Y and Z coils is 89.3001 ± 0.0045°, a value that remains stable despite variations in experimental parameters such as temperature and light power, thereby confirming the robustness of the method. Additionally, the measured gyromagnetic ratio is 6.9963 ± 0.0005 Hz nT−1, which closely matches the theoretical value of 6.9958 Hz nT−1, further validating the method's accuracy. The proposed method provides a more straightforward approach and has significant potential for widespread application across various atomic magnetometers, especially in miniaturized configurations. Furthermore, this method may be extended to the field of atomic gyroscopes.
