  2. Ferrofluid - Wikipedia

    en.wikipedia.org/wiki/Ferrofluid

    Ferrofluid is a liquid that is attracted to the poles of a magnet.It is a colloidal liquid made of nanoscale ferromagnetic or ferrimagnetic particles suspended in a carrier fluid (usually an organic solvent or water). [1]

  3. Magnetorheological fluid - Wikipedia

    en.wikipedia.org/wiki/Magnetorheological_fluid

    A magnetorheological fluid (MR fluid, or MRF) is a type of smart fluid in a carrier fluid, usually a type of oil. When subjected to a magnetic field , the fluid greatly increases its apparent viscosity , to the point of becoming a viscoelastic solid. [ 1 ]

  4. Ferromagnetism - Wikipedia

    en.wikipedia.org/wiki/Ferromagnetism

    Ferromagnetic materials spontaneously divide into magnetic domains because the exchange interaction is a short-range force, so over long distances of many atoms, the tendency of the magnetic dipoles to reduce their energy by orienting in opposite directions wins out. If all the dipoles in a piece of ferromagnetic material are aligned parallel ...

  5. Critical point (thermodynamics) - Wikipedia

    en.wikipedia.org/wiki/Critical_point...

    The liquid–liquid critical point of a solution, which occurs at the critical solution temperature, occurs at the limit of the two-phase region of the phase diagram. In other words, it is the point at which an infinitesimal change in some thermodynamic variable (such as temperature or pressure) leads to separation of the mixture into two ...

  6. Ferrimagnetism - Wikipedia

    en.wikipedia.org/wiki/Ferrimagnetism

    Like ferromagnetic substances, ferrimagnetic substances are attracted by magnets and can be magnetized to make permanent magnets. The oldest known magnetic substance, magnetite (Fe 3 O 4 ), is ferrimagnetic, but was classified as a ferromagnet before Louis Néel discovered ferrimagnetism in 1948. [ 2 ]

  8. Jellium - Wikipedia

    en.wikipedia.org/wiki/Jellium

    Jellium, also known as the uniform electron gas (UEG) or homogeneous electron gas (HEG), is a quantum mechanical model of interacting electrons in a solid where the positive charges (i.e. atomic nuclei) are assumed to be uniformly distributed in space; the electron density is a uniform quantity as well in space.

  9. Magnetostriction - Wikipedia

    en.wikipedia.org/wiki/Magnetostriction

    Internally, ferromagnetic materials have a structure that is divided into domains, each of which is a region of uniform magnetization.When a magnetic field is applied, the boundaries between the domains shift and the domains rotate; both of these effects cause a change in the material's dimensions.
