Transcript. Dipole-dipole forces occur between molecules with permanent dipoles (i.e., polar molecules). For molecules of similar size and mass, the strength of these forces increases with increasing polarity. Polar molecules can also induce dipoles in nonpolar molecules, resulting in dipole–induced dipole forces. Created by Sal Khan.Folded Dipole Antennas are an interesting variant on the familiar half- wavelength dipole design. The folded dipole offers more bandwidth than a classic half-wavelength dipole and can be fed directly with 300 ohm television twin lead, since the nominal impedance of this antenna runs between 280 and 300 ohms. I've made several antennas of this ...

Most dipoles will require a little "trimming or adding" to resonate at the desired frequency. Here is a good recommendation in 7 steps. 1. Cut your dipole wire some 2-3 % longer than the length given by the standard formula. 2. Make a note of the length obtained in step 1. 3. Raise the dipole to its operating height.A dipole moment is the product of the magnitude of the charge and the distance between the centres of the positive and negative charges in a system. It is denoted by the Greek letter ‘\mu’. Mathematically, DipoleMoment(μ) = Charge(Q) × distanceofseparation(r) The dipole moment is measured in Debye units.Single-band dipoles are among the easiest antennas to build.
