204.
Fig 424. Ship's Compass.
METHODS OF MAGNETIZATION.
635 an index for reading off on the card the direction to which the ship's head is turned. Sometimes a reflector is employed, as m in the first figure, in such a position that an observer looking in from behind can read oft' the indi- cated direction by reflection, and can at the same time sight a distant object whose mag- netic bearing is required. The origin of the compass is very obscure. The ancients were aware that the loadstone at- t...racted iron, but were ignor- ant of its directing property. The instrument came into use in Europe some time in the course of the thirteenth cen- tury.
503. Methods of Magnetization. The usual process of magnetizing a bar consists in rubbing it with or against a bar already magnetized. Different methods of doing this, called single touch, double touch, &c. , have been devised, in which magnetized bars of steel were the mag- netizing agents. Much greater power can, however, be obtained by means of electro-magnetism ; and the two following methods are now almost exclusively employed by the makers of magnets.
