bullet::::- 1600 — william gilbert publishes "de magnete, magneticisque corporibus, et de magno magnete tellure" ("on the magnet and magnetic bodies, and on that great magnet the earth"), europe's then current standard on electricity and magnetism. he experimented with and noted the different character of electrical and magnetic forces. in addition to known ancient greeks' observations of the electrical properties of rubbed amber, he experimented with a needle balanced on a pivot, and found that the needle was non-directionally affected by many materials such as alum, arsenic, hard resin, jet, glass, gum-mastic, mica, rock-salt, sealing wax, slags, sulfur, and precious stones such as amethyst, beryl, diamond, opal, and sapphire. he noted that electrical charge could be stored by covering the body with a non-conducting substance such as silk. he described the method of artificially magnetizing iron. his terrella (little earth), a sphere cut from a lodestone on a metal lathe, modeled the earth as a lodestone (magnetic iron ore) and demonstrated that every lodestone has fixed poles, and how to find them. he considered that gravity was a magnetic force and noted that this mutual force increased with the size or amount of lodestone and attracted iron objects. he experimented with such physical models in an attempt to explain problems in navigation due varying properties of the magnetic compass with respect to their location on the earth, such as magnetic declination and magnetic inclination. his experiments explained the dipping of the needle by the magnetic attraction of the earth, and were used to predict where the vertical dip would be found. such magnetic inclination was described as early as the 11th century by shen kuo in his "meng xi bi tan" and further investigated in 1581 by retired mariner and compass maker robert norman, as described in his pamphlet, "the newe attractive." the gilbert, a unit of magnetomotive force or magnetic potential, was named in his honor.
