WebAnswer (1 of 4): Everyone Dies™. EDIT: Scenario One can be safely discounted (because I didn’t read the question details…) Scenario One: The Neodymium-Iron-Boron magnet fails to work at the high temperatures seen at the Earth’s core. The magnetic field fails to work (You should have instead use... In physics and materials science, the Curie temperature (TC), or Curie point, is the temperature above which certain materials lose their permanent magnetic properties, which can (in most cases) be replaced by induced magnetism. The Curie temperature is named after Pierre Curie, who showed that magnetism was lost at a critical temperature. In its pure form, neodymium has magnetic properties—specifically, it is antiferromagnetic—but only at low temperatures, below 19 K (−254.2 °C; −425.5 °F). But some compounds of neodymium with transition metals such as iron are ferromagnetic, with Curie temperatures well above room temperature. These are used to make neodymium magnets. The strength of neodymium magnets is the result of several factors. The most important is that the birthday bts cake https://joellieberman.com
