During the course of their research, the researchers developed two families of neodymium–iron–boron magnets having quite different properties. Sagawa developed a family of sintered magnets.

This is due to their relatively low Curie point, which is the temperature above which a substance loses its magnetic properties. At room temperature, a pure bar of neodymium wouldn’t be a magnet ...

where the magnetic properties of the material break down. Thus, the laser cutter was set up to run a few passes over some neodymium magnets. By placing a magnetic viewing film over the magnet ...
