(physics) Birefringence of a material induced by an electric field due to partial orientation of its molecules.

(of a drug, etc.) To become active; to become effective. / (of a law, etc.) To come into force, to come into effect, to inure.

(physics) the reversible change in temperature that accompanies the change of magnetization of a ferromagnetic or paramagnetic material

(physics) The total expulsion of magnetic flux from the interior of a superconducting metal when it is cooled in a magnetic field below a critical temperature, near absolute zero, at which the transition to superconductivity takes place.

(physics) the resonant and recoil-free emission and absorption of gamma rays by atoms in the solid state; the basis of a type of spectroscopy with applications in both physics and chemistry

(physics) The splitting of single spectral lines into three (or more) in the presence of a magnetic field.

The ability (or the difficulty) of focusing one's attention on a single auditory source in a jumble of noises.

(physics) A form of the Zeeman effect that affects the spectral lines obtained when a light source is placed in a very strong magnetic field.

(transitive) To cause, bring about (an event); to accomplish, to carry out (a wish, plan etc.).

(physics) the magnetic self-attraction of parallel electric currents having the same direction; the restriction of a flowing plasma because of this attraction
