'Magnet' is derived from the legend of Magnes, or from the territory of Magnesia. Pliny states that Magnes, the shepherd, discovered it, and the legend told of him is that while carrying a message over Mount Ida he felt his feet clinging to the earth, to the iron ore which lay thickly upon the hill. Hence the name of the Magnet.

[6]
For example, in 1820 Hans Christian Ørsted of Copenhagen discovered the deflecting effect of an electric current traversing a wire upon a suspended magnetic needle. [11] This discovery gave a clue to the subsequently proved intimate relationship between electricity and magnetism which was promptly followed up by Ampère who some months later ...
Danish physicist Hans Christian Ørsted accidentally discovered that an electric field creates a magnetic field. 1820: One week after Ørsted's discovery, French physicist André-Marie Ampère published his law. He also proposed the right-hand screw rule. 1821: German scientist Thomas Johann Seebeck discovered thermoelectricity. 1825

From ancient history to the modern day, the clitoris has been discredited, dismissed and deleted -- and women's pleasure has often been left out of the conversation entirely. Now, an underground art movement led by artist Sophia Wallace is emerging across the globe to challenge the lies, question the myths and rewrite the rules around sex and the female body.
The story passed to Europe and became part of several epic tales. [1] [2] Europeans started to place magnetic mountains on their maps in the sixteenth century. A notable example is Gerardus Mercator, whose famous maps included a magnetic mountain or two near the North Pole. At first, he just placed a mountain in an arbitrary location; but later ...
