Definition of electrodynamics in US English:


plural noun

  • usually treated as singular The branch of mechanics concerned with the interaction of electric currents with magnetic fields or with other electric currents.

    • ‘He also laid the foundation for the science of electrodynamics.’
    • ‘For example, classical electrodynamics very effectively models light as a wave that can oscillate in different ways.’
    • ‘This can be done in the framework of the so-called ‘sharp boundary model’ that was previously used in the electrodynamics of semi-infinite plasma-like systems.’
    • ‘He worked on a wide range of topics in applied mathematics such as mathematical physics, potential theory and electrodynamics.’
    • ‘And it is strictly defined by continuity equation in both classical electrodynamics, and relativistic electrodynamics.’
    • ‘His contribution is unifying important parts of classical mechanics and Maxwell's electrodynamics.’
    • ‘In the early 20th century, it was realized that the stability of atomic matter could not be explained using the Maxwell equations of classical electrodynamics.’
    • ‘He gave a principle of conservation of energy in electrodynamics related to a force law of action-at-a-distance which, unlike that given by Coulomb, depended on velocities and accelerations.’
    • ‘Weber's later years at Göttingen were devoted to work in electrodynamics and the electrical structure of matter.’
    • ‘Suppose lamps were flying this way and that at various speeds, but that in some frame the light beams from those lamps were all traveling at 186,000 miles per second, just the speed predicted by the equations of electrodynamics.’
