remanence การใช้

• Again, nothing happens to the remanence until the field reaches.
• Colloquially, when a magnet is " magnetized " it has remanence.
• The field at which reaches zero is called the coercivity of remanence.
• :Data remanence cites very reliable sources that say " once ".
• Various techniques have been developed to counter data remanence.
• The most important component of remanence is that acquired when a rock formed.
• Superparamagnetic nanoparticles or nanoparticle clusters show no magnetic remanence.
• The Wohlfarth relations can be represented by linear plots of one remanence against another.
• These minerals have a much stronger response to the field and can have a remanence.
• Data remanence has also been observed in dynamic random-access memory ( DRAM ).
• Neodymium magnets, for example, have a remanence approximately equal to 1.3 teslas.
• Magnetically disordered minerals ( diamagnets and paramagnets ) contribute a weak magnetism and have no remanence.
• Thorough destruction of the underlying storage media is the most certain way to counter data remanence.
• Minerals that are Ferromagnetic minerals such as magnetite also can carry a remanent magnetization or remanence.
• Some kinds of remanence are undesirable and must be removed before the useful remanence is measured.
• Some kinds of remanence are undesirable and must be removed before the useful remanence is measured.
• Yet another kind of remanence can be obtained by demagnetizing the saturation remanence in an ac field.
• Yet another kind of remanence can be obtained by demagnetizing the saturation remanence in an ac field.
• A common method used to counter data remanence is to overwrite the storage media with new data.
• At zero field strength, the magnetization is offset from the origin by an amount called the remanence.
