The idea that the legend of Magnes the shepherd could be the origin of magnet, et al., and the legend itself has been criticized. Pliny's story is characterized in Gillian Turner's book North Pole, South Pole: The Epic Quest to Solve the Great Mystery of Earth’s Magnetism (2011) as "no doubt embellished by centuries of retelling."
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". [6]
The discovery of electromagnetic induction was made almost simultaneously, although independently, by Michael Faraday, who was first to make the discovery in 1831, and Joseph Henry in 1832. [77] [78] Henry's discovery of self-induction and his work on spiral conductors using a copper coil were made public in 1835, just before those of Faraday.
Frontispiece of the first edition of “ Magnes sive de arte magnetica” Dedication page of “ Magnes sive de arte magnetica” Frontispiece to Book III from the first edition of Magnes sive de arte magnetica. Magnes sive de Arte Magnetica ("The Lodestone, or the Magnetic Art") is a 1641 work by the Jesuit scholar Athanasius Kircher.
The force which emanates from the moon reaches to the earth, and, in like manner, the magnetic virtue of the earth pervades the region of the moon: both correspond and conspire by the joint action of both, according to a proportion and conformity of motions, but the earth has more effect in consequence of its superior mass; the earth attracts ...
After Davy and chemist William Hyde Wollaston unsuccessfully tried to build on Hans Christian Ørsted's discovery of the electromagnetic phenomena to harness the ability to create motion from electricity, Faraday was able to create his own device to create the first electric motor by applying electricity aligned along a magnet. Davy, bitter ...
One involves breaking a magnet in two and showing that both parts have a north and south pole. [7] He also dismisses the idea of perpetual motion. The third book has a general description of magnetic directions along with details on how to magnetize a needle. He also introduces his terella, or "little Earth". This is a magnetized sphere that he ...
Pivoting compass needle in a 14th-century handcopy of Peter's Epistola de magnete (1269). Petrus Peregrinus de Maricourt (Latin), Pierre Pelerin de Maricourt (French), or Peter Peregrinus of Maricourt [1] (fl. 1269), was a French mathematician, physicist, and writer who conducted experiments on magnetism and wrote the first extant treatise describing the properties of magnets.
