A remanencia, vagyis a marad\u00e9k m\u00e1gnesess\u00e9g (Br), annak a m\u00e1gnesess\u00e9gnek a szintje, amit egy \u00e1lland\u00f3 m\u00e1gnes megtart, miut\u00e1n a k\u00fcls\u0151 m\u00e1gneses mez\u0151t elt\u00e1vol\u00edtott\u00e1k.<\/strong><\/p>\n

A SmCo m\u00e1gnesek szint\u00e9n magas Br \u00e9rt\u00e9kkel rendelkeznek, de jobb h\u0151m\u00e9rs\u00e9kleti stabilit\u00e1ssal.
