Put the magnet inside a heavy plastic bag first. Turn the bag

out to remove iron filings.

You can collect iron filings by swishing a (plastic bagged)
magnet
around in a bowl of Wheaties cereal. Not kidding.

Do you suppose they are an added mineral supplement, or from wear
in
the packaging machinery?

There are chemical techniques for producing finely divided metal
particles. Ask a chem prof.

Ask me, I was a chemist before the Army taught me computer
electronics.

I needed while to remember "Raney".
This is the simple, low tech, non-toxic method we learned to prepare
finely divided nickel:

Check Adams catalyst. This technique can an used on Palladium and other
noble metals. Iron may need a different tack.
