  2. Larmor precession - Wikipedia

    en.wikipedia.org/wiki/Larmor_precession

    Larmor precession is important in nuclear magnetic resonance, magnetic resonance imaging, electron paramagnetic resonance, muon spin resonance, and neutron spin echo. It is also important for the alignment of cosmic dust grains, which is a cause of the polarization of starlight .

  3. Larmor formula - Wikipedia

    en.wikipedia.org/wiki/Larmor_formula

    The Larmor formula can only be used for non-relativistic particles, which limits its usefulness. The Liénard-Wiechert potential is a more comprehensive formula that must be employed for particles travelling at relativistic speeds. In certain situations, more intricate calculations including numerical techniques or perturbation theory could be ...

  4. Joseph Larmor - Wikipedia

    en.wikipedia.org/wiki/Joseph_Larmor

    He was born in Magheragall in County Antrim, the son of Hugh Larmor, a Belfast shopkeeper and his wife, Anna Wright. [3] The family moved to Belfast circa 1860, and he was educated at the Royal Belfast Academical Institution, and then studied mathematics and experimental science at Queen's College, Belfast (BA 1874, MA 1875), [4] where one of his teachers was John Purser.

  5. Van Vleck paramagnetism - Wikipedia

    en.wikipedia.org/wiki/Van_Vleck_paramagnetism

    While Curie and Larmor susceptibilities were well understood from experimental measurements, J.H. Van Vleck noticed that the calculation above was incomplete. If H {\displaystyle H} is taken as the perturbation parameter, the calculation must include all orders of perturbation up to the same power of H {\displaystyle H} .

  6. Rotating reference frame - Wikipedia

    en.wikipedia.org/wiki/Rotating_reference_frame

    In classical mechanics, centrifugal force is an outward force associated with rotation.Centrifugal force is one of several so-called pseudo-forces (also known as inertial forces), so named because, unlike real forces, they do not originate in interactions with other bodies situated in the environment of the particle upon which they act.

  7. Guiding center - Wikipedia

    en.wikipedia.org/wiki/Guiding_center

    If the field has a parallel gradient, a particle with a finite Larmor radius will also experience a force in the direction away from the larger magnetic field. This effect is known as the magnetic mirror. While it is closely related to guiding center drifts in its physics and mathematics, it is nevertheless considered to be distinct from them.

  9. Lorentz ether theory - Wikipedia

    en.wikipedia.org/wiki/Lorentz_ether_theory

    Joseph Larmor found a similar theory simultaneously, but his concept was based on a mechanical aether. A fundamental concept of Lorentz's theory in 1895 [A 1] was the "theorem of corresponding states" for terms of order v/c. This theorem states that a moving observer with respect to the aether can use the same electrodynamic equations as an ...
