A device for filtering systems for the separation of minute magnetizable particles down to particle sizes below 1 mu m from a gaseous or liquid medium introduced into a working volume permeated by a magnetic field in which the working volume is located in a rotating magnetic field and, in some embodiments, an agitated filter structure is disposed in the working volume to cause relatively large magnetic structures to be developed from the minute individual particles in a relatively weak rotating field, which structures can then be filtered out at a relatively high separating rate.
