单词 diamagnetic
释义

Definition of diamagnetic in English:

diamagnetic

adjective ˌdʌɪəmaɡˈnɛtɪkˌdaɪəmæɡˈnɛdɪk
Physics
  • (of a substance or body) tending to become magnetized in a direction at 180° to the applied magnetic field.

    〔物理〕(物质,物体)抗磁(性)的

    Example sentencesExamples
    • In the iron diamagnetic form, magnetic anisotropy arises from the heme, aromatic moieties, and elements of secondary structure.
    • For example, placing diamagnetic metals such as aluminium or zinc at the centre of the phthalocyanines improves the photosensitization of the compound for use in PDT.
    • The main impact of the diamagnetic components is dilution of the strongly magnetizable minerals.
    • Unfortunately, DNA displays a negative anisotropy in diamagnetic susceptibility that tends to align the DNA axis perpendicular to the magnetic field.
    • Any remaining magnetic effects in diamagnetic materials are produced by the orbiting electrons.

      Example sentencesExamples
      • The rest is done by the repulsive force of the diamagnet under the neodymium magnet.
      • A superconductor is a perfect diamagnet, but there is more than this involved in the Meissner effect.

      Example sentencesExamples

  • noun ˌdʌɪəˈmaɡnɪtɪz(ə)mˌdaɪəˈmæɡnəˌtɪzəm
    Physics

      Example sentencesExamples
      • Although diamagnetic effects are usually very small, one class of materials shows strikingly large diamagnetism: superconductors.
      • He followed his line of experiments which led him to discover diamagnetism.
      • The pi orbitals give rise to benzene's diamagnetism.

Origin

1846: coined by Faraday, from Greek dia 'through, across' + magnetic.
