Definition of Faraday effect in US English:

Faraday effect


  • The rotation of the plane of polarization of electromagnetic waves in certain substances in a magnetic field.

    • ‘Ferro-magnetic technology uses magnetooptical Faraday effect in which electromagnetic waves interact each other directly to create extremely fast switches (femtoseconds).’
    • ‘He discovered what is now called the Faraday effect, namely that if a beam of light is passed through a substance which polarises it, then the plane of polarisation is rotated by a magnetic field parallel to the ray of light.’
    • ‘Electrical properties such as dipole moments, magnetic properties, optical properties, and the Faraday effect all give important information about the structure of molecules as well.’
