85mm X 10mm Round Disc Magnet, Ferrite Y30BH, 40mm Center Hole, Black, Unbranded (Open Box)

Okay, so this is a big, strong magnet up for grabs.

It's a round disc shape, 85mm in diameter and 10mm thick, with a 40mm hole right through the middle.

Made from ferrite Y30BH material, which is a type of ceramic magnet.

It's black.

Just a heads-up, it's listed as 'open box'—so it's in excellent condition, but maybe the original packaging is missing.

Could have been a display model or something.

Still a solid magnet for projects, holding things, or whatever you need a strong magnetic field for.

Made in China.
