do i need the neodymium magenets ? i need 2 '? or can i do it with other tipe of mmagnets like the black ones dont know their name ... ????

@eliramone12 It can be done with one magnet, but definitely need neodymium. See earlier comments and responses as to the reason why.

do you need a specific type of magnet? Does it work with the normal black ones?

[daemn42]

@liceman2coool As I commented earlier, generally only a rare earth magnet is powerful enough to support both itself and the screw by the tiny tip of the screw. With a regular magnet it'll just fall off.

Hey! can i know the commercial name of this magnet? is it available in regular stores. Decided to do this for my project. Thanks a lot :)

@liceman2coool Just do a google search for "Rare earth magnets" or "Neodymium magnets"
