ocr: How can you get rid of magnetism? Ifthe domains of a magnet become jumbled up and lose their alignment, the magnet loses its magnetism. Some magnets fade away naturally: fairly soon after they're made. Others keep their magnetism for a veryl long time. The ability ofa material to keep its magnetism is called its "retention." Ifai material can be magnetized easily, it can also lose its magnetism easily. That's because its domains can be jumbled as easily as they can be aligned. This means a material that has a high permeability also has a low: retention. Iron, for example, can be magnetized mor ...
