2. Magnetoelastic filament - Wikipedia

   en.wikipedia.org/wiki/Magnetoelastic_filament

   Magnetoelastic filament. Magnetoelastic filaments are one-dimensional composite structures that exhibit both magnetic and elastic properties. Interest in these materials tends to focus on the ability to precisely control mechanical events using an external magnetic field. Like piezoelectricity materials, they can be used as actuators, but do ...

3. Magnet - Wikipedia

   en.wikipedia.org/wiki/Magnet

   A magnet is a material or object that produces a magnetic field. This magnetic field is invisible but is responsible for the most notable property of a magnet: a force that pulls on other ferromagnetic materials, such as iron, steel, nickel, cobalt, etc. and attracts or repels other magnets. A permanent magnet is an object made from a material ...

4. Heusler compound - Wikipedia

   en.wikipedia.org/wiki/Heusler_compound

   Heusler compounds are magnetic intermetallics with face-centered cubic crystal structure and a composition of XYZ (half-Heuslers) or X 2 YZ (full-Heuslers), where X and Y are transition metals and Z is in the p-block. The term derives from the name of German mining engineer and chemist Friedrich Heusler, who studied such a compound (Cu 2 MnAl ...

5. Maximum energy product - Wikipedia

   en.wikipedia.org/wiki/Maximum_energy_product

   The maximum energy product is defined based on the magnetic hysteresis saturation loop (B - H curve), in the demagnetizing portion where the B and H fields are in opposition. It is defined as the maximal value of the product of B and H along this curve (actually, the maximum of the negative of the product, −BH, since they have opposing signs ...

6. Ferromagnetism - Wikipedia

   en.wikipedia.org/wiki/Ferromagnetism

   Condensed matter physics. Ferromagnetism is a property of certain materials (such as iron) that results in a significant, observable magnetic permeability, and in many cases, a significant magnetic coercivity, allowing the material to form a permanent magnet. Ferromagnetic materials are noticeably attracted to a magnet, which is a consequence ...

7. Halbach array - Wikipedia

   en.wikipedia.org/wiki/Halbach_array

   A Halbach array (German: [ˈhalbax]) is a special arrangement of permanent magnets that augments the magnetic field on one side of the array while cancelling the field to near zero on the other side. [1][2] This is achieved by having a spatially rotating pattern of magnetisation. The rotating pattern of permanent magnets (on the front face; on ...
