Optimized Halbach array for focused magnetic drug targeting
Journal of Magnetism and Magnetic Materials, 2020Abstract Magnetic drug targeting (MDT) is a therapeutic method that delivers drug carriers containing magnetic nanoparticles to a target lesion by directing them using an external magnetic field. To minimize the possible side effects on the surrounding normal cells, focused magnetic drug targeting (FMDT) has been introduced, which allows drug ...

Calculation of the Static Forces Among the Permanent Magnets in a Halbach Array
IEEE Transactions on Magnetics, 2009This paper concerns the analysis of the interaction force among the permanent magnets (PM) in a Halbach array as used in a moving-magnet planar actuator. The goal is to analyze the magnitude of these forces and to what extent the mechanical construction of an aluminium plate, on which the permanent magnets are mounted, is deformed by the interaction ...

Analysis of axial field magnetic gears with Halbach arrays
2015 IEEE International Electric Machines & Drives Conference (IEMDC), 2015Magnetic gears can scale the torque and speed of rotary systems, while avoiding problems associated with transferring torque through physical contact. This work uses 3D finite element analysis to parametrically characterize the performance benefits which can be obtained from applying Halbach magnet arrays to axial field magnetic gears. It is found that
