On Earth, amateur and sometimes professional scientists collect dust from the tops of buildings or mountians (see also) and separate it with a magnet to obtain meteoric material. Not all meteoric material is ferromagnetic, but plenty is.

I am curious if anything has ever been done a similar test on Mars.

CNET's NASA Perseverance Mars rover investigates 'odd' rock, zaps it says:

Mars is a haven for meteorites, and it's always notable when a rover comes across one of these emissaries from space. Scientists are scrutinizing a holey rock spotted by NASA's Perseverance rover that bears a resemblance to meteorites seen elsewhere.

and here's another example from this answer to Who discovered “Egg Rock”? The Curiosity rover or people?

Egg rock

Question: I'm simply wondering; has anybody or anyrover dragged a magnet across martian soil to see what gets picked up? Has there been any magnetic measurements of specific rocks or particles of any kind?

note 1: I'd thought about asking a companion question about lunar regolith, but so much has been brought back to Earth by both the Soviet and US space programs that there was no need to do the work in situ.

note 2: If I had a rover on Mars I'd have it throw out a fishing line with many thin, flat rare earth magnets and "fish" for magnetic particles by dragging it along for a while, then go back and check it with a MAHLI-type inspection. Of course it would get hung up and jeopardize the mission and they wouldn't let me have any more rovers to play with.
