Dipole — This article is about the electromagnetic phenomenon. For other uses, see dipole (disambiguation). The Earth s magnetic field, approximated as a magnetic dipole. However, the N and S (north and south) poles are labeled here geographically, which… … Wikipedia
Dipole antenna — A schematic of a half wave dipole antenna connected to an unbalanced coaxial cable. Better practice is to connect the balanced dipole to the unbalanced line with a balun. A dipole antenna is a radio antenna that can be made of a simple wire, with … Wikipedia
Polarization density — In classical electromagnetism, the polarization density (or electric polarization, or simply polarization) is the vector field that expresses the density of permanent or induced electric dipole moments in a dielectric material. The polarization… … Wikipedia
magnetic dipole — Tiny magnet with subatomic dimensions, equivalent to the flow of electric charge around a loop. Examples include electrons circulating around atomic nuclei, rotating atomic nuclei, and single subatomic particles with spin. On a large scale, these … Universalium
Magnetic dipole — A magnetic dipole is the limit of either a closed loop of electric current or a pair of poles as the dimensions of the source are reduced to zero while keeping the magnetic moment constant. It is a magnetic analogue of the electric dipole, but… … Wikipedia
