Toroidal magnetic fieldNon-radial Alfvén oscillationsPulsating white dwarfsIn the context of white dwarf asteroseismology, we investigate the vibrational properties of a non-convective solid star with an axisy
Soft magnets are those materials easy to magnetize and demagnetize, while hard magnets are difficult to do so and retain strong magnetism after the removal of applied magnetic field. Hard magnets are also called permanent magnets, which include Neodymium magnets, SmCo magnets, AlNiCo magnets and ...
The magnetic field gradient is obtained by taking the discrete spatial derivative of the magnetic field. Solving Eq. (5) for the field at the locations \(x_i + x_\epsilon\) and \(x_i - x_\epsilon\) yields the magnetic field gradient by the given formula below: $$\begin{aligned} ...
the proton gyromagnetic ratio for proton precession magnetometer) and thus provide accurate (∼ 1nT) field intensity data with negligible drift. The utility of such total field measurements, however, is limited in certain geometries (N\S spreading ridges near the magnetic equator generate very low...
parallel to the flow in a T-junction microchannel can control droplet fragmentation, sorting, and merging. Hatami et al.23further explored this concept using simulations of a flow-focusing junction with an electric field. Their simulations resulted in a mathematical formula for predicting droplet ...
By measuring the difference between the applied magnetic field and the secondary magnetic field, one can determine the material-specific magnetic susceptibility. The magnetic induction of a sample, measured by a magnetic or electromagnetic sensor, is the sum of all the different entities of induced ...
In the centimeter–gram–second system magnetic field strength is determined using a different formula: Н=B— 4·π·М Magnetic field strength is measured in amperes per meter (A/m), while in the centimeter–gram–second system it is measured in oersteds (Oe). ...
The overall process of pressing perception, as shown in Fig.4a, involves pressing and rolling a ball (15 mm in diameter) on the magnetic skin. The real-time data changes in the magnetic field signals resulting from different pressing positions are transmitted to a computer for signal processi...
Different change of the magnetic field between these two points can be obtained by using Eqs. (6) and (9), Figure 4 (a) The location of the magnetic dipole of \(\overrightarrow{\mathrm{m}}\) relative to the atomic magnetometer. (b) Moving and mapped mesh for stationary and linearly...
Field of the Invention The present invention relates to a magnetization method and a magnetization apparatus for forming a magnetized state of a sine wave that presents at least a half wavelength pulse of the sine wave in a one-dimensional region of a magnetic body, specifically a magnetic body...
