Dark matter is not known to have any intrinsic magnetic properties or polarity. Dark matter is believed to interact only gravitationally with other matter, and not through the electromagnetic force.
While some models of dark matter propose that it could interact with other matter through forces beyond gravity, such as the weak or strong nuclear force, there is currently no direct evidence to support these models.
Therefore, it is currently believed that dark matter does not have magnetic polarity or any other intrinsic electromagnetic properties.
