Some magnetite might not be that magnetic so you may havea "duff" lump. Rather than buy a new bit - magnetise it yourself, no one will know

How magnetic is magnetite?
Submitted by Louise_Ellender on Mon, 04/02/2007 - 13:38.Hi there,
I have to confess I'm not a geologist but I have a geology question. I have bought some magnetite on-line as a prop for an educational project I'm helping out with on physics (we're discussing electromagnetism). The rocks don't appear to be magnetic at all - they don't attract paperclips or any other metal objects I can find.
Can anyone tell me just how magnetic is magnetite supposed to be - I want to know if I've been scammed or if magnetite is just only really weakly magnetic.
Any help or advice you can offer would be great. Thanks
Louise Ellender
