The stronger magnetic fields can be hazardous to mechanical and electronic devices, as they can erase magnetic media such as floppy disks and credit cards, and magnetize watches and the shadow masks of CRT-type monitors at a greater distance than other types of magnet.
The AlNiCo technically have a slightly stronger field (specifically, increased magnetic flux density), but they become demagnetized easily in the presence of other magnetic fields. Because NdFeB magnets have comparable strength and do not demagnetize as easily, they have largely replaced AlNiCo magnets, especially in applications where there is ...
N52 (Long Island bus) BMW N52, an automobile engine; HMS Trident (N52), a submarine of the Royal Navy; HNoMS Vidar (N52), a minelayer of the Royal Norwegian Navy; Nostromo SpeedPad n52, a computer gaming peripheral; Okamura N-52, a Japanese sport aircraft; Neodymium magnet grade for one of the strongest (N30-N55) types
The specific strength is bounded to be no greater than c 2 ≈ 9 × 10 13 kN⋅m/kg, where c is the speed of light. This limit is achieved by electric and magnetic field lines, QCD flux tubes , and the fundamental strings hypothesized by string theory .
Given a set of contigs, the N50 is defined as the sequence length of the shortest contig at 50% of the total assembly length. It can be thought of as the point of half of the mass of the distribution; the number of bases from all contigs longer than the N50 will be close to the number of bases from all contigs shorter than the N50. For example ...
Strengthening of materials is useful in many applications. A primary application of strengthened materials is for construction. In order to have stronger buildings and bridges, one must have a strong frame that can support high tensile or compressive load and resist plastic deformation.
The BMW N52 is a naturally aspirated straight-6 petrol engine which was produced from 2004 to 2015. The N52 replaced the BMW M54 and debuted on the E90 3 Series and E63 6 Series . The N52 was the first water-cooled engine to use magnesium/aluminium composite construction in the engine block. [ 1 ]
Sheet metal is metal formed into thin, flat pieces, usually by an industrial process. Thicknesses can vary significantly; extremely thin sheets are considered foil or leaf, and pieces thicker than 6 mm (0.25 in) are considered plate, such as plate steel, a class of structural steel. Sheet metal is available in flat pieces or coiled strips.
