Where to Buy Magnet Rod for Solenoid? Find Out Here!

[X20A]

Hi...
I'm doing a solenoid for my project.
But I don't know where to buy the magnet rod.
I had look for a lot of place but doesn't have the magnet.
Do anyone here know where can I get the magnet?
Thank you.

Try a hardware store, most have steel rod
or you can just get a big bolt there, that should work fine.
