WebJul 1, 1999 · This paper deals with demagnetizing factors of magnetic fluids. To obtain correct magnetizations of magnetic substances, it is necessary to make corrections for demagnetizations when they are measured in a magnetic field. But we have little knowledge about the demagnetizing factors of magnetic fluids [1]. We have tried to evaluate them … Web1 day ago · Bussi Demagnetizing Systems is a leading provider of demagnetization equipment, and the merger with Brockhaus, a well-established manufacturer of magnets and magnetic assemblies, is expected to ...

The demagnetizing field, also called the stray field (outside the magnet), is the magnetic field (H-field) generated by the magnetization in a magnet. The total magnetic field in a region containing magnets is the sum of the demagnetizing fields of the magnets and the magnetic field due to any free currents or … See more Single domain One way to remove the magnetic poles inside a ferromagnet is to make the magnetization uniform. This occurs in single-domain ferromagnets. This still leaves the surface … See more • Aharoni, Amikam (1996). Introduction to the Theory of Ferromagnetism. Clarendon Press.
