You don't think too much.

Was busy removing STAINLESS steel screws from the car, throwing them into a magnetic tray as I went.

Picked it up, and the whole lot fell out all over the floor. I stood there, looking, wondering how that happened.


I also once spent ages retrieving a dropped stainless nut inside the door panel with a magnetic on a stick.

Plonker!

(but I have done similar things, so many times...)

And, before someone says it, some stainless steel is magnetic - but mostly it isn't.

It was magnetic enough to attach, but not enough to overcome gravity.
