  2. Electric dipole moment - Wikipedia

    en.wikipedia.org/wiki/Electric_dipole_moment

    The electric dipole moment is a measure of the separation of positive and negative electrical charges within a system: that is, a measure of the system's overall polarity. ...

  3. Dynamic toroidal dipole - Wikipedia

    en.wikipedia.org/wiki/Dynamic_toroidal_dipole

    In classical electrodynamics, the dynamic toroidal dipole arises from time-dependent currents flowing along the poloidal direction on the surface of a torus. [1] In relativistic quantum mechanics, spin contributions to the toroidal dipole needs to be taken into account. [2] Toroidal dipole moments are odd under parity and time-reversal symmetries.

    Transition dipole moment, the electrical dipole moment in quantum mechanics; Molecular dipole moment, the electric dipole moment of a molecule. Bond dipole moment, the measure of polarity of a chemical bond; Electron electric dipole moment, the measure of the charge distribution within an electron; Magnetic dipole moment, the measure of the ...

  5. Dipole - Wikipedia

    en.wikipedia.org/wiki/Dipole

    The size of the induced dipole moment is equal to the product of the strength of the external field and the dipole polarizability of ρ. Dipole moment values can be obtained from measurement of the dielectric constant. Some typical gas phase values given with the unit debye are: [7] carbon dioxide: 0; carbon monoxide: 0.112 D; ozone: 0.53 D

  6. Electron electric dipole moment - Wikipedia

    en.wikipedia.org/.../Electron_electric_dipole_moment

    The electron's electric dipole moment (EDM) must be collinear with the direction of the electron's magnetic moment (spin). [1] Within the Standard Model, such a dipole is predicted to be non-zero but very small, at most 10 −38 e⋅cm, [2] where e stands for the elementary charge.

  7. Polarization density - Wikipedia

    en.wikipedia.org/wiki/Polarization_density

    When a dielectric is placed in an external electric field, its molecules gain electric dipole moment and the dielectric is said to be polarized. Electric polarization of a given dielectric material sample is defined as the quotient of electric dipole moment (a vector quantity, expressed as coulombs*meters (C*m) in SI units) to volume (meters ...

    Angelina Jolie balked at a question regarding whether there should be a biopic about her life.. When Jolie, 49, and her Maria director Pablo Larraín spoke with the U.K.'s The Times to promote ...

  9. Neutron electric dipole moment - Wikipedia

    en.wikipedia.org/wiki/Neutron_electric_dipole_moment

    Parity (P) and time-reversal (T) violation due to an electric dipole moment. μ denotes the magnetic dipole moment of the neutron, while d is the electric dipole moment. A permanent electric dipole moment of a fundamental particle violates both parity (P) and time reversal symmetry (T). These violations can be understood by examining the ...
