Magnet - jimag

Japanese: 磁石 - じしゃく

("Shaku" is the Go-on pronunciation of "stone") [1] [noun] ① A natural mineral with magnetic properties. Mainly magnetite and red magnetite. Jiseki. ※Ryōiki (810-824), Vol. 1 "The desire for profit and greed for wealth is greater than the raising of a magnetic iron mountain and the lying of iron." ※Kanazoshi, Chiekan (1660), "The hands of Kannon are made of a magnetic magnet. " [Cao Zhi - Jiao Zhi Shi] ② A colloquial term for a magnetic compass or magnetic rose. A directional measuring device that uses the north-pointing (south-pointing) properties of a magnet. It began to be used for navigation at least in the late Middle Ages, and became widespread in the early modern period, with the reverse needle , a uniquely Japanese invention, being highly valued. A magnetic plate. A magnetic needle. A magnetic needle. A south-pointing needle. ※Holland Tensetsu (1795): "The north and south of a magnet are caused by the rigid, rotating energy of the heavens." ③ An object that is magnetic and therefore has the property of attracting iron. They can be classified into permanent magnets, which are magnetic without the aid of an external magnetic field, and temporary magnets, which are magnetic only when an external magnetic field is applied. Both belong to the ferromagnetic material, and the former are called magnetically hard, while the latter are called magnetically soft. These properties are expressed in terms of residual magnetization and coercive force. Magnet. Porcelain. ※Kabuki/Kamenogi (1742): "Iron scraps are mixed with wax to make oil, and this is used to draw up the iron with a magnet. " ④ A device that generates a magnetic field. Permanent magnets, electromagnets, superconducting magnets, etc. [2] Kyogen. Each school. On his way to Tokyo, a man is about to be sold to a slave trader who chases after him with a sword.
