Examples of coercivity in a Sentence

Recent Examples on the Web However, energy assisted magnetic recording where energy is applied to very stable magnetic recording media (having high magnetic coercivity) to allow it to be written on, is the best hope for increasing the linear density of magnetic recording. Tom Coughlin, Forbes, 10 Dec. 2023 This characteristic is essential for producing a good and useful permanent magnet, because without it the magnet can not have what is known as high coercivity—the ability of the magnet to resist demagnetization. IEEE Spectrum, 15 Nov. 2023 That, in turn, can be exploited to achieve high coercivity, the essential property that lets a permanent magnet stay magnetized. IEEE Spectrum, 22 Mar. 2023 The list of attributes needed for a commercially successful permanent magnet includes high field strength, high coercivity, tolerance of high temperatures, good mechanical strength, ease of manufacturing, and lack of reliance on elements that are scarce, toxic, or problematic for some other reason. IEEE Spectrum, 22 Mar. 2023 These manufacturing techniques allow Toyota to lose 20 to 50 percent of the neodymium necessary to make a NdFeB magnet without losing performance or coercivity. Megan Geuss, Ars Technica, 28 Feb. 2018 Performance of the new magnet (in terms of coercivity) is slightly better at the top of its operating-temperature spread—above about 270 degrees Fahrenheit—which is right where and when peak performance in an electric vehicle would be needed. Bengt Halvorson, Car and Driver, 27 Feb. 2018
