90 °Countersunk NdFeB Disc Magnet Warnings:
Neodymium magnets attract each other with almost twice the force that they use to attract
steel objects.They also attract each other through very large distances, even small
magnets will attract each other through the thickness of your finger!

We occasionally get inquiries and manufacturing prints identifying a custom magnet shape using the abbreviation Neo. Because shorthand works – both internally and in discussions with our customers – we likewise sometimes refer to a Neodymium magnet as Neo or NdFeB. Of the rare earth element magnets, Neo magnets are the most commonly specified because they have the highest known energy product for their mass. One might possibly expect the Neo name to mean “new” – and that could be a reasonable assumption based on the fact that they were initially created relatively recently in 1984. The abbreviated name, however, actually comes from the element Neodymium – or Nd.

But there is a bit of a “new” twist to the naming story. In 1885, Carl Auer von Welsbach discovered that a substance known as (and previously misclassified as an element) ‘Didymium’ was actually a mixture of two entirely new elements. Welsbach successfully reacted Didymium to form nitrate salts, which he then fractionally crystallized from nitric acid to yield pink Neodymium and greenish-brown Praseodymium salts. Welsbach chose the name Praseodymium, which from Greek indicates ‘green twin.’ Compounds of praseodymium are green. Neodymium was named with ‘neos didymos’ – Greek for ‘new twin,’ reflecting Neodymium’s close association with praseodymium.
