Hi, I'm looking for supermagnets and steel balls for my project. The magnets are cubes with 12mm sides and it is very powerful. They look something like these:


And the steel balls are 5/8th inch (around 1.5875 cm) in diameter.


Can anyone help? Please...

Thank you.

The one i need is quite big, around 1.6 cm in diameter. Is it available? I found a place selling them but is too expensive.

thank you very much
