In a classical wave picture, the slowing can be explained by the light inducing electric polarization in the matter, the polarized matter radiating new light, and the new light interfering with the original light wave to form a delayed wave.
A close coupling of magnetization and polarization via magnetoelectric and magnetodielectric effects holds promise for new generations of storage media with both magnetic and electric polarization and opens the possibility of electrically reading/writing magnetic memory devices.
As the voltage increases, the current stresses the material (by electric polarization) beyond its dielectric limit (termed strength) into a stage of electrical breakdown, marked by an electric spark, where the material transforms from being an insulator into a conductor (as it becomes increasingly ionized).
Instead, electric polarization occurs.
Some solids, notably certain crystals, have permanent electric polarization.
The larger the tendency for charge distortion (also called electric polarization), the larger the value of the permittivity.
This lag of electric polarization behind the applied electric field is ferroelectric hysteresis, named by analogy with ferromagnetic hysteresis.
This sudden shift of electric charge across the postsynaptic membrane changes the electric polarization of the membrane, producing the postsynaptic potential, or PSP.
In electric polarization, the centre of positive charge within an atom, molecule, or crystal lattice element is separated slightly from the centre of negative charge.
Ion flux can lead to cell membrane depolarization (less negative charge across the cell), which leads to an action potential a brief electric polarization that results in a nerve impulse that is conveyed to the brain.
The effects of the dielectric on electrical phenomena are described on a large, or macroscopic scale by employing such concepts as dielectric constant, permittivity, and polarization (see electric polarization).
