dipole
dipole (ˈdaɪpəʊl) [f. di-2 + pole n.2] 1. A pair of non-coincident equal and opposite electric charges or magnetic poles (usu. but not necessarily close together); an object, esp. a molecule, atomic particle, etc., having such charges or poles; dipole moment, the product of the distance between the ...

Dipole - Wikipedia
The magnetic field of a sphere with a north magnetic pole at the top and a south magnetic pole at the bottom. By comparison, Earth has a south magnetic pole near its north geographic pole and a north magnetic pole near its south pole. In physics, a dipole (from Greek δίς (dis) 'twice', and πόλος (polos) 'axis') is an electromagnetic phenomenon which occurs in two ways:

Dipole Calculator | Antenna Length Calculator
Jan 18, 2024The formulae to calculate the dipole antenna and leg length are: L = 468 / f, l = L /2, where: L - Length of the dipole antenna in feet; l - Length of each arm of the dipole in feet; and. f - Frequency. Then, multiply the values of L and l by 0.3048 to convert them to meters. Łucja Zaborowska, MD, PhD candidate.

Dipole Moments - Chemistry LibreTexts
Jan 30, 2023Dipole Moment. When two electrical charges, of opposite sign and equal magnitude, are separated by a distance, an electric dipole is established. The size of a dipole is measured by its dipole moment (\(\mu\)). Dip ole moment is measured in Debye units, which is equal to the distance between the charges multiplied by the charge (1 Debye eq uals \(3.34 \times 10^{-30}\; C\, m\)).

Why is water a dipole? - Chemistry Stack Exchange
Yep, it has to do with the orbitals. $\ce{CO2}$ is linear, so even though the $\ce{C-O}$ bonds have individual dipole moments, the overall dipole moment is zero as these cancel out (they point in opposite directions, as shown in the diagram below). On the other hand, $\ce{H2O}$ is "bent", which means that the individual dipole moments of the bond are at an angle to each other.

Dipole speaker
A dipole speaker enclosure in its simplest form is constructed by mounting a loudspeaker driver on a flat panel. Especially at lower frequencies, dipole drivers tend to be large and flat, and necessarily open at both front and back. wikipedia.org

Please explain how to build a six meter ham radio dipole antenna
hello Randy here k7a GE this video is to show you how to put together a simple 6 meter dipole antenna this video is part of my get on 6 series to get you and the shield of the coax to the other part of the dipole antenna if we remember our formula for a length of a dipole you divide 468 by the megahertz

3.7: Geometry and Dipole Moment - Chemistry LibreTexts
Using the cross bow arrow shown below we can show that it has a net dipole. The net dipole is the measurable, which is called the dipole moment. Dipole moment is equal to the product of the partial charge and the distance. The equation for dipole moment is as follows. μ = δ × d (3.7.1) (3.7.1) μ = δ × d. with.

Does there exist a dipole field on $S^2$ differing by at most a minus sign between antipodal points? Consider the two-sphere $S^2 \subset \mathbb{R}^3$. By a _dipole field_ on $S^2$, I mean a continuous function $f \c...
I think this should work: construct a vector field om $\mathbb R^2-${$(0,0)$} with exactly one zero, and use the stereographic projection to pull it back to $\mathbb S^2$. Maybe a good point to make here, is that the fact that the stereographic projection is a diffeomorphism allows you to pushforwar...

Stereo dipole
Thanks to the cross-talk cancellation method, a stereo dipole can render an acoustic stereo image nearly 180 degrees wide (single stereo dipole) or 360 degrees (dual or double stereo dipole). wikipedia.org

omnidirectional antennas and the dipole antenna This article on Cisco's website is the clearest explantion of omnidirectional antennas I've found. What isn't so clear to me is... 1) Why is the dipole antenna the mos...
The dipole antenna is the most common because it is inherently simple and very inexpensive to produce. A dipole antenna is often just a straight piece of wire.
