Polarization (economics) Economists refer to the polarization of the labor force when middle-class jobs—requiring a moderate level of skills, like autoworkers’ jobs—seem to disappear relative to those at the bottom, requiring few skills, and those at the top, requiring greater skill levels. [ 1] The structure of job opportunities in the ...
In classical electromagnetism, polarization density (or electric polarization, or simply polarization) is the vector field that expresses the volumetric density of permanent or induced electric dipole moments in a dielectric material. When a dielectric is placed in an external electric field, its molecules gain electric dipole moment and the ...
Electric susceptibility. In electricity (electromagnetism), the electric susceptibility ( ; Latin: susceptibilis "receptive") is a dimensionless proportionality constant that indicates the degree of polarization of a dielectric material in response to an applied electric field. The greater the electric susceptibility, the greater the ability of ...
Polarizability. Polarizability usually refers to the tendency of matter, when subjected to an electric field, to acquire an electric dipole moment in proportion to that applied field. It is a property of particles with an electric charge. When subject to an electric field, the negatively charged electrons and positively charged atomic nuclei ...
Polarization (electrochemistry) In electrochemistry, polarization is a collective term for certain mechanical side-effects (of an electrochemical process) by which isolating barriers develop at the interface between electrode and electrolyte. These side-effects influence the reaction mechanisms, as well as the chemical kinetics of corrosion and ...
The commonly used symbol denoting the polarity of a device or adapter consists of a black dot with a line leading to the right and a broken circle (like the letter "C") surrounding the dot and with a line leading to the left. At the ends of the lines leading right and left are found a plus sign (+), meaning positive, also sometimes referred to ...
Ferroelectricity. Ferroelectricity is a characteristic of certain materials that have a spontaneous electric polarization that can be reversed by the application of an external electric field. [1][2] All ferroelectrics are also piezoelectric and pyroelectric, with the additional property that their natural electrical polarization is reversible.
Polarization (also polarisation) is a property of transverse waves which specifies the geometrical orientation of the oscillations. [1][2][3][4][5] In a transverse wave, the direction of the oscillation is perpendicular to the direction of motion of the wave. [4] A simple example of a polarized transverse wave is vibrations traveling along a ...
