What factor reduce the magnetization of a perninant magnet

In addition to heating the magnet (mentioned above), I think that banging the magnet with a sledge hammer (without breaking the magnet into pieces) will reduce the magnetization by breaking up some of the magnetic domains in the magnetized metal or ceramic material.
