Dipole (Noun)
Meaning 1
A pair of equal and opposite electric charges or magnetic poles separated by a small distance.
Classification
Nouns denoting natural objects (not man-made).
Examples
- The electric dipole consists of two point charges of equal magnitude but opposite sign.
- Magnetic dipoles are created by loops of current and are found in some atoms.
- The dipole moment of the molecule is determined by the orientation of its polar bonds.
- Electric dipoles interact with other charges and dipoles, producing the phenomenon of electrostatic attraction or repulsion.
- The magnetic field of the earth is generated by the motion of molten iron, which creates magnetic dipoles that align to form the earth's magnetic field.
Hyponyms
Meaning 2
An aerial half a wavelength long consisting of two rods connected to a transmission line at the center.
Classification
Nouns denoting man-made objects.
Examples
- A dipole antenna is often used for radio broadcasting because it has a simple design and works efficiently.
- The center-fed dipole, with each element one-quarter wavelength long, is an effective antenna configuration.
- If you want to build a simple and functional antenna, try making a half-wave dipole for the desired frequency.
- A common amateur radio antenna is the half-wave dipole, where each leg of the antenna is one-quarter wavelength long.
- In order to install a full-wave dipole antenna, ensure each element is a half wavelength and align them in the desired direction.
