... iso-vector meson fields, i.e., rho and pi, thus the iso-vector current and magnetic moment are still enhanced. Even if rho meson is considered, the enhancement of iso-vector current still can not be reduced significantly because of the small rho-N coupling constant. P. G. Blunden, Nucl. Phys. A 464 ...

... A freely suspended magnet always comes to lie in the geographic north-south direction because the earth behaves as a magnet. Near the earth’s geographic north pole is the magnetic south and near the earth’s geographic south pole is the magnetic north. So, a freely suspended magnet’s poles get attrac ...

Compass



A compass is an instrument used for navigation and orientation that shows direction relative to the geographic cardinal directions, or ""points"". Usually, a diagram called a compass rose, shows the directions north, south, east, and west as abbreviated initials marked on the compass. When the compass is used, the rose can be aligned with the corresponding geographic directions, so, for example, the ""N"" mark on the rose really points to the north. Frequently, in addition to the rose or sometimes instead of it, angle markings in degrees are shown on the compass. North corresponds to zero degrees, and the angles increase clockwise, so east is 90 degrees, south is 180, and west is 270. These numbers allow the compass to show azimuths or bearings, which are commonly stated in this notation.The magnetic compass was first invented as a device for divination as early as the Chinese Han Dynasty (since about 206 BC), and later adopted for navigation by the Song Dynasty Chinese during the 11th century. The use of a compass is recorded in Western Europe and in Persia around the early 13th century.
