At present, the magnetic signals generated by common artificial beacons change periodically with sinusoidal law, and there is a multi-value problem in measuring target orientation using phase information of signals. According to characteristics Halbach array, kind beacon based on array studied. This has signal aggregation, which can avoid facilitate extraction information. Firstly, model establ...

Temperature degrading of magnet material is of mayor interest in many applications. Segmented rare earth Halbach arrays are subject to an augmented temperature degrading effect due to local demagnetisation. This paper presents results using a parameter-based material demagnetisation model. Measurement results of high temperature Halbach arrays are validated with 2D FEA.

This paper presents a novel 2-D magnet array with gaps and staggers, which is especially suitable for magnetically levitated planar motor with moving magnets. The magnetic flux density distribution is derived by Fourier analysis and superposition. The influences of gaps and staggers on high-order harmonics and flux density were analyzed, and the optimized design is presented. Compared with the ...

We optimized the magnetic field homogeneity of two canonical designs for mobile microfluidic nuclear resonance (NMR) applications: parallel magnets with an air gap and a modified Halbach array. Along influence sample length, general design guidelines will be presented. For fair comparison, sensitive length has been chosen to same as size between ensure enough space transmitting receiving unit, ...
