  2. Magnus effect - Wikipedia

    en.wikipedia.org/wiki/Magnus_effect

    The Magnus effect is a phenomenon that occurs when a spinning object is moving through a fluid. A lift force acts on the spinning object and its path may be deflected in a manner not present when it is not spinning. The strength and direction of the Magnus effect is dependent on the speed and direction of the rotation of the object. [1]

  3. Spin wave - Wikipedia

    en.wikipedia.org/wiki/Spin_wave

    The operator + will increase the z-projection of the spin at position i back to its low-energy orientation, but the operator will lower the z-projection of the spin at position j. The combined effect of the two operators is therefore to propagate the rotated spin to a new position, which is a hint that the correct eigenstate is a spin wave ...

  4. Stern–Gerlach experiment - Wikipedia

    en.wikipedia.org/wiki/Stern–Gerlach_experiment

    If one measures the spin along a vertical axis, electrons are described as "spin up" or "spin down", based on the magnetic moment pointing up or down, respectively. To mathematically describe the experiment with spin + particles, it is easiest to use Dirac's bra–ket notation. As the particles pass through the Stern–Gerlach device, they are ...

  5. Magnetic mirror - Wikipedia

    en.wikipedia.org/wiki/Magnetic_mirror

    By the late 1970s, many of the design problems were considered solved, and Lawrence Livermore Laboratory began the design of the Mirror Fusion Test Facility (MFTF) based on these concepts. The machine was completed in 1986, but by this time, experiments on the smaller Tandem Mirror Experiment revealed new problems. In a round of budget cuts ...

  6. Spin (physics) - Wikipedia

    en.wikipedia.org/wiki/Spin_(physics)

    The conventional definition of the spin quantum number is s = ⁠ n / 2 ⁠, where n can be any non-negative integer. Hence the allowed values of s are 0, ⁠ 1 / 2 ⁠, 1, ⁠ 3 / 2 ⁠, 2, etc. The value of s for an elementary particle depends only on the type of particle and cannot be altered in any known way (in contrast to the spin ...

  7. Thomas precession - Wikipedia

    en.wikipedia.org/wiki/Thomas_precession

    Llewellyn Thomas (1903 – 1992). In physics, the Thomas precession, named after Llewellyn Thomas, is a relativistic correction that applies to the spin of an elementary particle or the rotation of a macroscopic gyroscope and relates the angular velocity of the spin of a particle following a curvilinear orbit to the angular velocity of the orbital motion.

  8. Spin polarization - Wikipedia

    en.wikipedia.org/wiki/Spin_polarization

    In particle physics, spin polarization is the degree to which the spin, i.e., the intrinsic angular momentum of elementary particles, is aligned with a given direction. [1] This property may pertain to the spin, hence to the magnetic moment , of conduction electrons in ferromagnetic metals, such as iron , giving rise to spin-polarized currents .

  9. Bloch equations - Wikipedia

    en.wikipedia.org/wiki/Bloch_equations

    In physics and chemistry, specifically in nuclear magnetic resonance (NMR), magnetic resonance imaging (MRI), and electron spin resonance (ESR), the Bloch equations are a set of macroscopic equations that are used to calculate the nuclear magnetization M = (M x, M y, M z) as a function of time when relaxation times T 1 and T 2 are present.
