It's midnight and i've just ordered some magnets


Neodymium atom x 2
Iron tom x 14
Boron x 1
Method A:

Prepare by pulverizing an ingot precursor and liquid phase, sintering the magnetically aligned powder into dense blocks

then heat treat, cut to shape, surface treat and magnetize.

Method B:

Melt spin a thin ribbon of the Nd-Fe-B alloy.

pulverize ribbon into particles

mixed with polymer

either compression or injection mold into bonded magnets

... i had to buy 100 of them because they are RARE EARTH MAGNETS.
