coercivity การใช้

• The wider the outside loop is, the higher the coercivity.
• The low coercivity reduces that energy loss associated with hysteresis.
• Thus coercivity measures the resistance of a ferromagnetic material to becoming demagnetized.
• The applied field where the data line crosses zero is the coercivity.
• In such materials, the coercivity is controlled by nucleation.
• If the temperature rises then the coercivity would be lower.
• Domain walls move easily within the magnet and have a low coercivity.
• The field at which reaches zero is called the coercivity of remanence.
• The width of the middle section is twice the coercivity of the material.
• Cunife has a magnetic coercivity of several hundred oersteds.
• To obtain much coercivity, impurity control is critical in the fabrication process.
• Point defects can nucleate reversed domains in ferromagnets and dramatically affect their coercivity.
• Their low coercivity also contributes to low loss.
• Materials with low coercivity are said to be magnetically " soft ".
• The length of the arrow shows its magnetization and its width shows its coercivity.
• The tape was a half-inch cobalt doped tape with a 550 oersted coercivity.
• This results in a much larger coercivity.
• Hematite exhibited temperature-dependent magnetic coercivity values ranging from 289 to 5, 027 Oe.
• "Soft " magnets ( low coercivity ) are used as cores in electromagnets.
• High coercivity stripes are resistant to damage from most magnets likely to be owned by consumers.
