Innovative Hybrid Halbach Array for Steering Magnetic Nanoparticles Through a Bifurcation

Abstract Magnetic nanoparticles are used in a wide range of medical applications. However, the accurate steering particles through vascular system is still an open research question. Thus, this paper introduces novel hybrid magnetic array for bifurcation. The consists permanent plus electromagnets and based on Halbach structure. It combines advantages strong field low-cost magnets with adjustability electromagnets. investigated numerically 3D model using COMSOL Multiphysics. In simulations, propagation symmetrical bifurcation analyzed discrete coil currents −10A to 10 A. results reveal that low negative −1A −0.5 A, influence can be almost completely eliminated, only 0.5% 0.9 %, respectively, were trapped by magnets. outperforms reference fully built Overall, proposed much more flexible, force adjusted precisely compared
