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.

  • $\begingroup$ Thank you for your answer. But i exactly wanted to know is there any co relation between magnetic anomaly and spatial distribution of dust storm in Mars? $\endgroup$ – jyotirmoy Jun 13 at 6:10
  • $\begingroup$ @jyotirmoy I think Oscar's implying that the influence of the magnetic field(s) on the dust particles would be negligible, thus there wouldn't be a correlation. Of course, this is inference, not evidence, so you don't have to accept the reasoning. $\endgroup$ – called2voyage Jun 13 at 19:51
