MAGNETIC SEPARATOR FOR MAGNETIC PARTICULATE

摘要

PROBLEM TO BE SOLVED: To miniaturize a magnetism separator for hybridization and improve magnetism-shielding capability during off of magnetism.

SOLUTION: A magnet holder 32 holds a magnet 34. The end 50 in the magnetization direction on a shielding side is held in such a way that the end 48 in the magnetization direction on an open side is exposed. The on-off of magnetism is controlled by rotation of the holder 32. A non-magnetic spacer 52 is disposed between the end 50 and the holder 32. A shielding-enhancing cover is optionally provided so as to cover the end 48 during off of magnetism and contact with the holder 32 on both sides of the covered end 48.
