William Gilbert, Earth's Magnetic Field, 1600
Bildnummer 12651504
| The dip of the Earth's magnetic field at various latitudes. De Magnete, Magneticisque Corporibus, et de Magno Magnete Tellure (On the Magnet and Magnetic Bodies, and on That Great Magnet the Earth) is a scientific work published in 1600 by William Gilbert. De Magnete was influential because of the inherent interest of its subject matter, but also for the rigorous way in which Gilbert described his experiments and his rejection of ancient theories of magnetism. William Gilbert (1544-1603) was an English physician, physicist and natural philosopher. He was the first to argue that the centre of the Earth was iron, and he considered an important and related property of magnets was that they can be cut, each forming a new magnet with north and south poles. He invented the first electrical measuring instrument, the electroscope, in the form of a pivoted needle he called the versorium. | |
