21. K u, which in turn is higher for a material with a higher magnetic coercivity . 22. Coercivity happens to be temperature dependent.23. Low coercivity stripes are easily damaged by even a brief contact with a magnetic purse strap or fastener. 24. Coercivity is usually measured in oersted or ampere / meter units and is denoted " H"25. In the late media devices, acicular oxides were used which produced the coercivity values necessary to record. 26. As the external field surpasses the hard material's coercivity , the hard magnet gets fully demagnetized. 27. They used principles including Carbon-14 and low-coercivity magnetism in order to make fraud more difficult. 28. It has an extremely high magnetic permeability ( approximately 800000 N / A 2 ) and a low coercivity . 29. It is recommended to design the field 3 times higher than the intrinsic coercivity to fully magnetize a material. 30. In the exchange spring magnet, the hard phase has high coercivity and the soft phase has high saturation.
