  • Permanent Magnets

    Coercivity and Remanence in Permanent Magnets A good permanent magnet should produce a high magnetic field with a low mass, and should be stable against the influences which would demagnetize it. The desirable properties of such magnets are typically stated in terms of the remanence and coercivity of the magnet materials. When a ferromagnetic material is magnetized in one direction, it will

  • Permanent Magnet MagLab

    Permanent magnets are materials where the magnetic field is generated by the internal structure of the material itself. Inside atoms and crystals you have both electrons and the nucleus of the atom. Both the nucleus and the electrons themselves act like little magnets, like little spinning chunks of electric charge, and they have magnetic fields inherent in the particles themselves. There's

  • The material used for permanent magnet has:

    The coercivity tells you how much (reverse) magnetic field would have to be applied to demagnetize the material. The materials with high remanence and high coercivity from which permanent magnets are made are sometimes said to be "magnetically hard" to contrast them with the magnetically soft materials from which transformer cores and coils for electronics are made.

  • Elektropermanentmagnet Wikipedia

    Ein Elektropermanentmagnet ist ein spezieller Magnet, dessen äußere Magnetwirkung mit einem Stromimpuls ein- und ausgeschaltet werden kann.. Er besteht aus einem Elektromagnet mit einem Kern aus magnetisch semihartem Material und einem Permanentmagnet (aus magnetisch hartem Material). Ist der semiharte Kern gegenläufig zum harten Kern magnetisiert, so heben sich deren magnetische

    Soft magnetic materials are characterized by low values of coercivity (H c <10 3 A m –1), while the coercivity of hard magnetic materials (usually permanent magnets) is higher than 10 4 A m –1. Finally, semihard magnetic materials (mostly storage media) have coercivities in between the above two values. In addition, there exist a number of sophisticated magnetic materials with unusual
