Four Cylinder Halbach Array for Magnetic Navigation System
2009 3rd International Conference on Bioinformatics and Biomedical Engineering, 2009The magnetic navigation system has been widely used for the minimally invasive interventions. The four cylinder Halbach array was introduced into the magnetic navigation system to decrease the high cost. A small model was manufactured and measured. The experiment results indicated that the orientation of magnetic field could be precisely controlled by ...

Application and Evaluation of Halbach-Like Magnet Arrays to Magnetic Drug Targeting
Advanced Materials Research, 2011Among the proposed techniques for delivering drugs to specific locations within the human body, magnetic drug targeting (MDT) surpasses because of its noninvasive character and its high targeting efficiency. In this study, two novel arrangements of permanent magnets, Halbach array and spin-Halbach, were introduced to improve the magnetic force acting ...

CHAPTER 5. Hardware Developments: Halbach Magnet Arrays
2015Halbach magnet arrays are very attractive for mobile NMR, because they generate very homogeneous and strong magnetic fields per magnet mass and have negligible stray fields. First of all, they are introduced as idealized geometries. Then the problems arising from the practical necessity to truncated and discretize the ideal Halbach is discussed in ...

Analysis of the Planar Magnetic Field of Linear Permanent Magnet Halbach Array
Applied Mechanics and Materials, 2011In this paper, the analytical solution to the planar magnetic field of a linear permanent magnet Halbach array is researched on. First, the magnetic field of a current surface is derived from the magnetic field produced by the molecular current of the permanent magnet.

Modeling and analysis of Halbach magnet array with pyramidal magnet in planar motor
International Journal of Applied Electromagnetics and Mechanics, 2018In this paper, the changing of magnet shape in Halbach magnet array of planar motor is analyzed for the magnetic flux density. It is the rectangular magnets that are replaced by pyramidal magnets. The magnetic flux density of Halbach magnet array with rectangular magnets is derived by Fourier series and scalar potential.

Magnetic design consideration of a Magnetic Lead Screw with Halbach Array
2015This paper presents the novel design of a Magnetic Lead Screw (MLS) with magnetic thread of Halbach Arrays. The MLS where designed and build, tests indicated a stall force which where 12 % lower than calculated in 3D FE. This is explained by demagnetization of the magnet during stall, the behavior of the demagnetization has been studied and the results

The effect of the Halbach array on FSPM machine magnetic field
2015This paper deals with improvement of behavior of the flux-switching permanent magnet machine through adding the Halbach array on the outer diameter of the stator. Different variants of Halbach arrays were modeled and compared. A comparison of obtained results shows an interesting way of flux-switching permanent magnet machine magnetic field shielding.
