Dipole

In physics, there are several kinds of dipole: An electric dipole is a separation of positive and negative charges. The simplest example of this is a pair of electric charges of equal magnitude but opposite sign, separated by some distance. A permanent electric dipole is called an electret, A magnetic dipole is a closed circulation of electric current. A simple example of this is a single loop of wire with some constant current flowing through it, A current dipole is a flow of current from a sink of current to a source of current within a medium. Current dipoles are often used to model neuronal sources of electromagnetic fields that can be measured using MEG or ...
