We calculate the disk and boundary layer luminosities for accreting rapidly rotating neutron stars with low magnetic fields in a fully general relativistic manner. Rotation increases the disk luminosity and decreases the boundary layer luminosity. A rapid rotation of the neutron star substantially modifies these quantities as compared to the static limit. …
A new analytical magnetic circuit hybrid model (AMCHM) is proposed to predict uneven air gap magnetic field for disc planetary permanent magnet machine (DP-PM machine) with segmented gap Halbach array.

In this work, based on the high binding ability of antimicrobial peptide (AMP) and polymyxin B (PMB) to bacteria, combined with magnetic separation technology, a new enzyme-free colorimetric strategy was constructed to achieve visual detection of Gram-negative bacteria in complex samples.
Disc magnets are the most common shaped magnet used in today's major markets and industries due to their versatility and economic cost. Because of their high magnetic strength in compact shapes and round, wide, flat surfaces with large magnetic pole areas, they are used for numerous industrial, technical, commercial and consumer applications.
The 3-disc magnetic separator is mainly used to dryly separate granular minerals, such as titanium ore, zircon, rutile, feldspar, quartz, tungsten-tin ore and coltan. The selection of metal minerals or the iron remover of non-metallic materials. It's also the separation and purification of magnetic and non-magnetic minerals.
Eddy currents can produce significant drag, called magnetic damping, on the motion involved. Consider the apparatus shown in Figure 23.7.1 23.7. 1, which swings a pendulum bob between the poles of a strong magnet. (This is another favorite physics lab activity.) If the bob is metal, there is significant drag on the bob as it enters and leaves ...

In this paper, we demonstrated a low-cost method for detecting bacterial infection in the early stage. We designed a hand-powered centrifugal microfluidic (CMF) disc with magnetic chitosan beads (MCBs) to detect specific circulating antibodies in human whole blood. Nine identical units was used for calibration curve plotting and …
Figure 22.2.5 22.2. 5: An electromagnet with a ferromagnetic core can produce very strong magnetic effects. Alignment of domains in the core produces a magnet, the poles of which are aligned with the electromagnet. Figure 22.2.6 22.2. 6 shows a few uses of combinations of electromagnets and ferromagnets. Ferromagnetic …
Electromagnets create a magnetic field through the application of electricity. When you introduce the current, either from a battery or another source of electricity, it flows through the wire. This creates a magnetic field around the coiled wire, magnetizing the metal as if it were a permanent magnet.
The standard design of a disc separator features up to three high-intensity electromagnetic discs, with each disc set at a different height from a feed conveyor. …
5 Uses for Disc Magnets. Apex Magnets has over 100 options for disc magnets, and for good reason! These circular, flat magnets are the most commonly used magnet shape. Neodymium disc magnets have significant strength—pull forces range from 5 ounces to 1174.9 pounds per magnet, while diameters range from 2 millimeters to 6 inches—and …
The on-disk magnetic stirrer introduced in this study merges the concept of magnetic stirrer into the centrifugal microfluidics for the first time. Arising from the continuous spinning of the disk, the rotation of the stirrer can be accomplished using some permanent magnets fixed in particular locations.
Faraday’s law of induction states that an electromotive force is induced by a change in the magnetic flux.
A magnetic hard disk drive (HDD) is a data storage device that uses magnetism to store and retrieve digital information. It consists of one or more rigid magnetic platters coated with a magnetic material, positioned on a …
