Halbach magnets are a source of homogeneous magnetic field in an enclosed volume while keeping stray fields at minimum. Here, we present the design, construction, and characterization for stack two rings with 10 cm inner diameter providing (<100 ppm over 1.0×1.0×0.5cm3) around 105 mT, which will be used diamond based microwave-free widefield imaging setup. The final is performed novel fiberized...

Next-generation advanced-accelerators such as the PWFA, and beam-radiation interactions such as inverse-Compton scattering, depend on increased beam-density to achieve superior results. The photoinjector has enabled the production of high-brightness beams that are desirable for experiments with critical dependencies on bunch length and emittance. Along with the production of shorter and lower-e...

Abstract The mapping of magnetic fields is an important task for characterizing permanent magnets, their systems, and the various devices that use magnets. However, commercial this are quite expensive difficult to acquire. In study, a design process automatized setup utilizing 3D printer was proposed via do-it-yourself approach using common parts found in laboratory. We used two purposes: creat...

Foreign body ingestion is a common problem in children. Ingested foreign bodies include coins, needles, pins and button batteries. Ingestion of multiple magnets is very rare and poses a unique hazard of intestinal obstruction in children. The ingested magnets may reside in different loops of intestine and attract each other causing necrosis of the intervening wall of intestine. We present the c...

This paper firstly explains how the stator slot PM (SSPM) machines have evolved from conventional flux reversal (FRPMs), by placing magnets over tooth tips or between tips. The influence of and configurations five types SSPM with various structures in slots, two three without tips, on electromagnetic performance are then investigated compared. It shows that, no matter what winding (non-overlapp...

This article presents the electromagnetic and mechanical design as well experimental testing results for a 9.5:1 gear ratio, series connected, coaxial magnetic (MG) use in marine hydrokinetic generator. A two- three-dimensional magnetostatic finite-element analysis (FEA) sizing was also conducted torque density comparison between using nested or MG typology is presented. To achieve high density...

Abstract In applications requiring a large magnetic force, permanent magnets with non-parallel magnetization directions can be assembled in Halbach array to generate gradient of flux density. The saturation magnets, however, brings fundamental limit on the performance this configuration. present work, we investigate experimentally assembly cuboid bulk, grain melt-textured YBa 2 Cu 3 O <?CDATA $...

Abstract Optimal design results in maximum motor performance. This type of BLDC has undergone innovations such as surface-mounted permanent magnet (SPM) with variants as: radial magnet, rectangular and bread-loaf. The position the outer rotor is a that commonly applied to electric bicycles. attached side body allows for superior torque In this paper, we present an analysis on bicycle been imple...

An analytical technique is developed for predicting the performance of a bonded Halbach oriented anisotropic magnet, with due account of partial alignment of the NdFeB powder during injection molding. The predicted performance of a 12-pole injection molded, Halbach oriented magnet is compared with measurement.
