PURPOSE:To simplify a device without needing a mechanical mobile by providing a magnetic wall and magnetic field adding means forming this magnetic wall. CONSTITUTION:Total space is divided into two spaces 5 and 6 by means of partitions 4, magnetic poles 1, 2 and a magnetic wall 3. An interaction of a magnetic field and gas or liquid is generated in the vicinity of the magnetic wall 3, and as a result, the movement of gas or liquid or heat or dust contained in gas or liquid between two spaces 5, 6 interposed with the magnetic wall 3 is restrained or cut off. That is to say, the magnetic wall 3 works as if it were a transparent unseen curtain. |
