“…research, achieving heightened precision in magnetic field control has assumed greater significance. For instance, in precision measurement, controlling the magnetic field to the nearzero range can reduce the relaxation state of alkali metal atoms in the spin-exchange relaxation-free atomic magnetometer, thus improving the test accuracy [8][9][10]. Accurate modulation of the magnetic field finds applications in cancer treatment [11], regulation of cellular functionality [12], and other aspects [13].…”

The demand for nonlinear magnetic fields (NMF) spans diverse domains, encompassing medical applications like drug transportation and aerospace applications such as attitude control. Existing designs of magnetic field coils predominantly focus on uniform and gradient fields as the complexity of magnetic field distribution often leads to intricate solution processes. This paper presents a novel approach to coil design, addressing the challenge of NMF distribution by reconstructing the characteristic matrix within the traditional target field method (TFM). To solve the overdetermined equations involved, we incorporate an improved particle swarm optimization (IPSO) algorithm into the TFM framework. A pair of symmetrical and asymmetrical coils are designed and the effectiveness of this method is verified by comparing the simulated and experimental results.
