magnetic field lines: ... Earth is largely protected from the solar wind, a stream of energetic charged particles emanating from the sun, by its magnetic field. These particles would strip away the ozone layer, which protects Earth from harmful ultraviolet rays. Earth''s magnetic field is generated by a feedback loop in the liquid outer core: Current loops generate magnetic fields; a changing ...

The matrix plays a key role in determining the performance of a highgradient magnetic separator; it provides the carrier for the magnetic particles to be captured and transported to the nonmagnetic field as magnetic product. Highgradient magnetic separation (HGMS) of ultrafine hematite with the finest 1 mm rod matrix has been investigated on a pilot pulsating HGMS separator. The results of ...

Sources of atmospheric particulate matter. Some particulates occur naturally, originating from volcanoes, dust storms, forest and grassland fires, living vegetation and sea activities, such as the burning of fossil fuels in vehicles, stubble burning, power plants, road dust, wet cooling towers in cooling systems and various industrial processes, also generate significant amounts of ...

In transverse (perpendicular) pressing, the field is perpendicular to the compaction pressure. Because the small powder particles are elongated in the direction of magnetic alignment, transverse pressing yields better alignment, thus a higher energy product. Compacting powder in hydraulic or mechanical presses limits the shape to simple crosssections that can be pushed out of the die cavity ...

Abstract. Recent progress in several areas of fine particle magnetism are discussed. These are: microstructure and morphology of particles, estimates of H K distributions in particle assemblies, intrinsic surface magnetization of γFe 2 O 3 particles, anisotropy enhancement by surface treatment, and the long range magnetization order in assemblies of nominally superparamagnetic Fe particles ...

· Therefore, it is necessary to develop a bacterial capture system with ligandindependent magnetic nanoparticles to capture the bacteria, especially under low concentrations. Many scientists have investigated the nature of the electric charge of bacteria. Bechhold (1904) was the first to find the fact that bacterial cells carry a negative charge ...

Magnetic particle spectroscopy (MPS) measures the nonlinear magnetic response of MNPs exposed to an oscillating magnetic field – like MPI, but without spatial encoding. MPS can be used to test the MPI performance of MNPs within a very short time [64]. Additionally, it is a very sensitive method for the characterization of magnetic nanoparticles capable of quantifying particles and also able ...

Magnetic inks (particles suspended in a liquid) are used more widely than dry powders. They are applied by lowpressure spray, dipping or brushing; it is important to use plenty of ink and to allow time for the particles to flow over the surface and migrate to any cracks. On dark surfaces a very thin layer of white paint can be applied to give a higher contrast indication.

Magnetic particle Inspection (MPI) is a nondestructive testing (NDT) process for detecting surface and shallow subsurface discontinuities in ferromagnetic materials such as iron, nickel, cobalt, and some of their alloys. The process puts a magnetic field into the part. The piece can be magnetized by direct or indirect magnetization.

· Ability of Magnetic NPs to Capture E. coli. Figure 3 shows the general experimental procedure of bacteria capture. NPs were mixed with a solution of bacteria and incubated at room temperature for 10 min. Subsequently, we used a permanent magnet to capture the "magnetized" bacteria (magnetic nanoparticles bounded to the cell surface) onto the wall of the tube.

We discovered that small magnetic nanocubes spontaneously assemble into highly ordered chains, sheets, and cuboids in solution by applying a magnetic field. We elucidate how these assemblies are formed by working out the threedimensional equilibrium arrangement of the dipoles. This classic physics problem turned out to be amazingly complex. The discovered solution selfassembly process is of ...

Magnetism is a class of physical phenomena that are mediated by magnetic fields. Electric currents and the magnetic moments of elementary particles give rise to a magnetic field, which acts on other currents and magnetic moments. Magnetism is one aspect of the combined phenomenon of most familiar effects occur in ferromagnetic materials, which are strongly .

Further downstream, both magnetic nanoparticles of the ferrofluid and nonmagnetic particles are depleted. Lower concentration of magnetic nanoparticles downstream lead to weaker magnetophoretic and magnetoconvective forces making the capture zone appears to be larger. Fewer nonmagnetic particles make the capture zone looks hollow.

· We introduce a new class of spherical colloids that reversibly selfassemble into welldefined nonlinear structures by virtue of "magnetic patches". This assembly is driven by tunable magnetostatic binding forces that originate from microscopic permanent magnets embedded underneath the surface of the particles. The resulting clusters form spontaneously in the absence of external ...

The particle velocity model developed in this study described the dynamic motion of fine dust particles along the magnetized mesh wires in a low Stokes regime. The numerically evaluated velocity contour of the particles modeled the critical path lines indicating the threshold positions for magnetic collection. The velocity contour was determined using the parameters such as particle size ...

Primary fine iron or magnetic particles are often present in the raw material. This originates from primary processing, transportation, or even naturally occurs in the original material. Secondary fine iron originates from a larger tramp metal source that has been reduced in size during the process. Typically, this could be from a nail, screw or bolt that has been through a size reduction ...
