  2. Permanent magnet motor - Wikipedia

    en.wikipedia.org/wiki/Permanent_magnet_motor

    A permanent magnet motor is a type of electric motor that uses permanent magnets for the field excitation and a wound armature. The permanent magnets can either be stationary or rotating; interior or exterior to the armature for a radial flux machine or layered with the armature for an axial flux topology.

  3. Structural channel - Wikipedia

    en.wikipedia.org/wiki/Structural_channel

    The structural channel, C-channel or parallel flange channel (PFC), is a type of (usually structural steel) beam, used primarily in building construction and civil engineering. Its cross section consists of a wide "web", usually but not always oriented vertically, and two "flanges" at the top and bottom of the web, only sticking out on one side ...

  4. Electrical steel - Wikipedia

    en.wikipedia.org/wiki/Electrical_steel

    The magnetic properties of electrical steel are tested using the internationally standard Epstein frame method. [18] The size of magnetic domains in sheet electrical steel can be reduced by scribing the surface of the sheet with a laser, or mechanically. This greatly reduces the hysteresis losses in the assembled core. [19]

  5. Electropermanent magnet - Wikipedia

    en.wikipedia.org/wiki/Electropermanent_magnet

    An electropermanent magnet or EPM is a type of permanent magnet in which the external magnetic field can be switched on or off by a pulse of electric current in a wire winding around part of the magnet. The magnet consists of two sections, one of "hard" (high coercivity) magnetic material and one of "soft" (low coercivity) material. The ...

  6. Permeability (electromagnetism) - Wikipedia

    en.wikipedia.org/wiki/Permeability...

    For example, 4% electrical steel has an initial relative permeability (at or near 0 T) of 2,000 and a maximum of 38,000 at T = 1 [5] [6] and different range of values at different percent of Si and manufacturing process, and, indeed, the relative permeability of any material at a sufficiently high field strength trends toward 1 (at magnetic ...

  8. Ferromagnetism - Wikipedia

    en.wikipedia.org/wiki/Ferromagnetism

    For example, this temporary magnetization inside a steel plate accounts for the plate's attraction to a magnet. Whether or not that steel plate then acquires permanent magnetization depends on both the strength of the applied field and on the coercivity of that particular piece of steel (which varies with the steel's chemical composition and ...
