1. Adjective:

   • Bipolar, dipolar: Describes a system, object, or phenomenon that has or is characterized by two opposite poles, such as magnetic poles (north and south) or electrical poles (positive and negative).
   • Two-pole: Specifically refers to a device or component having two terminals or poles.

2. Noun:

   • Dipole: In physics, a pair of equal and oppositely charged or magnetized poles separated by a small distance.
   • Bipolar device: A component, such as a specific type of diode or transistor, that operates with two charge carriers (electrons and holes).
