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.

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.
