The discovery of the property of magnets. Magnets were first found in a natural state; certain iron oxides were discovered in various parts of the world, notably in Magnesia in Asia Minor , that had the property of attracting small pieces of iron, which is shown here.
1st century AD – Pliny in his Natural History records the story of a shepherd Magnes who discovered the magnetic properties of some iron stones, "it is said, made this discovery, when, upon taking his herds to pasture, he found that the nails of his shoes and the iron ferrel of his staff adhered to the ground".

On April 24, 1873, Nature announced the publication with an extensive description and much praise. [4] When the second edition was published in 1881, George Chrystal wrote the review for Nature. [5] Pierre Duhem published a critical essay outlining mistakes he found in Maxwell's Treatise. [6] Duhem's book was reviewed in Nature. [7]
Ancient humans discovered the property of magnetism from lodestone. An illustration from Gilbert's 1600 De Magnete showing one of the earliest methods of making a magnet. A blacksmith holds a piece of red-hot iron in a north–south direction and hammers it as it cools. The magnetic field of the Earth aligns the domains, leaving the iron a weak ...
From his initial discovery in 1821, Faraday continued his laboratory work, exploring electromagnetic properties of materials and developing requisite experience. In 1824, Faraday briefly set up a circuit to study whether a magnetic field could regulate the flow of a current in an adjacent wire, but he found no such relationship. [51]
William Gilbert (/ ˈ ɡ ɪ l b ər t /; 24 May 1544? – 30 November 1603), [1] also known as Gilberd, [2] was an English physician, physicist and natural philosopher. He passionately rejected both the prevailing Aristotelian philosophy and the Scholastic method of university teaching. He is remembered today largely for his book De Magnete (1600).
Title page of 1628 edition. 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 the English physician and scientist William Gilbert.
Ars Magnesia (The Magnetic Art) was a book on magnetism by the Jesuit scholar Athanasius Kircher in 1631. [1] It was his first published work, written while he was professor of ethics and mathematics, Hebrew and Syriac at the University of Würzburg. [2] [3] It was published in Würzburg by Elias Michael Zink. [4]
