The position of the absorption and emission bands remain almost unchanged in solvents of different polarity as the dipole moment and transition dipole are orthogonal to each other.
In ferroelectrics, upon lowering the temperature below , a spontaneous dipole moment is induced along an axis of the unit cell.

Appliances are inspected for damage, and various measurements are made to the appliances' earth continuity, insulation, polarity, and physical condition.
Signals are often transmitted over balanced connections using the differential mode, meaning the wires carry signals of opposite polarity to each other (for instance, in an XLR connector, pin 2 carries the signal with normal polarity, and pin 3 carries an inverted version of the same signal).

If a stereophonic or other binaural signal is plugged into such a jack, one channel (usually the right) will be subtracted from the other (usually the left), leaving an unlistenable L − R (left minus right) signal instead of normal monophonic L + R. Reversing the polarity at any other point in a balanced audio system will also result in this effect at some point when it is later mixed-down with its other channel.
Modern HOm trains run on realistic-looking two-rail track, which is powered by direct current (varying the voltage applied to the rails to change the speed, and polarity to change direction), or by Digital Command Control (sending commands to a decoder in each locomotive).
Pom1 is a polarity protein kinase in fission yeast, Schizosaccharomyces pombe (S. pombe), that localizes to cell ends and regulates cell division.
In the fruit fly Drosophila melanogaster, segment polarity genes help to define the anterior and posterior polarities within each embryonic parasegment by regulating the transmission of signals via the Wnt signaling pathway and Hedgehog signaling pathway.
The Dillon-Wagoner Graviton Polarity Generator, known colloquially as the spindizzy is a fictitious anti-gravity device imagined by James Blish for his series Cities in Flight.
