element method (FEM); meanwhile, mass computer resource and time for parametric design or optimization are wasted in three dimension (3-D) FEM, a concise and efficient 3-D analytical approach is put forward for the calculation of the air-gap magnetic field and torque of coaxial magnetic gears...
A system of a finite number of harmonically-trapped fermions in one dimension, in the presence of a static magnetic field, is studied within the framework ... HA Al-Khzon,HB Ghassib,MK Al-Sugheir - 《Revue Canadienne De Physique》 被引量: 0发表: 2015年 ...
The initial magnetic domain structure was created by first saturating the NiFe strips through a small alpha tilt (1.9°) and applying a large objective lens field which is gradually reduced to zero. The normalized \({M}_{x}\) and \({M}_{y}\) of the NiFe layer, calculated from defocus...
PROBLEM TO BE SOLVED: To improve operability between an element and external magnetic field by making a resistance changing rate represented by a specific formula to be negative when a specified external magnetic field is applied, and constituting the element in a manner that the absolute value of...
These results comprise the theories of Magnetic Topological Quantum Chemistry (MTQC) and fermionic symmetry-based indicators (double SIs)7,30,31,32,51, which apply to all possible 3D magnetic and nonmagnetic crystals with mean-field Hamiltonians. We have also determined the physical bases of all...
(γ) according to the following formulaω = γB0, whereγis a constant describing the gyromagnetic ratio of a particular nuclear species (i.e., for protonγ = 267.56 × 106rad/s/T). If to the static B0a second alternating magnetic field (B1) is applied in the ...
(no magnetic field) defined in ( 2.14 ) ( 2.11 ), and denote by \(\sigma (h^d)\) its spectrum. let \(\sigma _p^\phi \) be the collection of eigenvalues of \(h^b.\) then we have the following description of the topological structure and point/continuous decomposition of the ...
The permeability of a ferromagnet (or ferrimagnet) is a function of applied field, temperature, and frequency. For electronic transformer and inductor applications where a small field is impressed, the initial relative permeability, μi (often measured at B = 4 mT), is the most useful quantity...
Reversal of a fluid flow upon parameter changes or perturbation is closely related to intriguing phenomena such as geomagnetic reversal, a drastic change in a planet's magnetic field where the positions of magnetic north and south are interchanged1. Typically, for a planet there is dynamo action...
The NEP was performed in microglial (MG) brain cells, which are highly sensitive for neuro-viral infection and were selected as target for nano-neuro- therapeutics. When the ac-magnetic field optimized (60 Oe at 1 kHz), MENPs were taken up by MG cells without affecting cell health (...
