Do I have to worry about temperature with neodymium magnets?
Yes. Neodymium Iron Boron magnets are sensitive to heat. If a magnet heated above its maximum operating temperature (176F (80°) for standard N grades) the magnet will permanently lose a fraction of its magnetic strength. Different grades of neodymium different maximum operating and Curie temperatures.
