poling

The term "poling" can refer to different processes. In the context of ceramics, it specifically describes a technique used to align magnetic dipoles in piezoelectric materials. This is achieved by cooling the ceramic through its Curie point while under the influence of an electric field, directing the dipoles along a specific axis.1

Piezoelectric ceramics, such as lead zirconate titanate (PZT), generate a voltage when subjected to mechanical pressure and change their dimensions when exposed to an electromagnetic field. These properties are utilized in various applications, including frequency standards for clocks, transducers for microphones, and igniters for gas stoves.12

Other meanings of "poling" include a method of excavation using "poling boards" or simply the act of punting.34
