The social media post for the clip, as well as another video posted to Twitter here, also claims that the dust’s magnetism is evidence of “chemtrails".
However, experts say magnetism is typical of Saharan dust.
Saharan dust’s characteristic red colour reflects the presence of small amounts of haematite, a weakly-magnetic mineral, she said.
However, air pollution-derived metals are usually present in much lower quantities than the naturally-sourced metal-bearing dust particles, she said.
Saharan dust contains naturally magnetic particles, including haematite, which gives the dust its characteristic red colour.
