Since we know most dust particles on Mars are magnetic, I was wondering if they might be affected by the Martian magnetic field.
Can the Martian magnetic field have any effect on the spatial distribution of a Martian dust storm?
We would not expect much of an effect when the strongest Martian magnetic field is only about 2% of Earth's. Mars does not have a global dynamo like Earth, the Martian dynamo having long since collapsed; its field comes from extrinsic sources such as the solar wind or, perchance, those storm-driven dust particles. In numerical terms, quoting from the source above, is a maximum of 1500 nT on Mars vs 65,000 nT on our big blue marble.
