Discussion history Outline of the story told historically. Basic ideas that even young children now know. Keep everything to an introductory level. Miletus is now on the western coast of Turkey in what was then a region of Greece known as Ionia source of the chemical term ion, but that's another story.
A piece of magnetite with an exceptionally strong magnetic action is sometimes called a lodestone.
A nice quote from Thales would be nice here. Some minerals such as magnetite Fe3O4 are obviously magnetic. Chinese navigators knew that magnetic rocks align themselves north-south the south-pointing spoon.
The compass in real sense was created by a Chinese geomantic omen master in late Tang Dynasty, who originally used it for divination. The north magnetic pole of a compass points in the general direction of the north geographic pole of the Earth.
Since opposite magnetic poles attract, this means that the south magnetic pole of the Earth is somewhere near its north geographic pole. Next comes Peter Peregrinus as he is known in English a.
Peter wrote what is commonly known as the Epistole de Magnete or Letter on the Magnet. De Magnete was the text in which Gilbert revealed the results of his research on magnetism and attempted to explain the nature of magnets and the five motions associated with magnetic phenomena. The work met with great acclaim and was republished in and T he Edexcel IGCSE in Physics is designed for use in schools and colleges.
It is part of a suite of the IGCSE suite of science qualifications offered by Edexcel. The course gives students the opportunity to experience physics within the context of their general education. About This Course.
Recognised internationally by universities, schools and employers as the equivalent to a UK GCSE; our IGCSE Combined Science Double Award is perfect for those seeking to supplement their qualifications outside of the classroom.

There is a magnetic field around. Aug 01, · Physics - EDEXCEL IGCSE - Magnetism and Electromagnetism Section 6 - Magnetism and Electromagnetism: Magnetically hard material - retains its magnetism for a long time.
It is also hard to demagnetize. Magnetically soft material - loses its magnetism almost as soon as it leaves the magnetic field. EDEXCEL IGCSE / CERTIFICATE IN PHYSICS Magnetism and Electromagnetism.
