1296Peter Peregrinus

conducted experiments of magnetism and wrote the first treatise describing existing magnetic properties.

In 1269, he wrote a letter to a friend discussing the magnetism called "Epistle of Magnete" which explains how magnets attract and repel each other and how to identify the poles of a compass.

1296 Discovery of the Epistle of Magnete (compass):

Maricourt takes a stone, magnet, which one was round and one needle that is guided immediately by the action of the magnet. When the needle stops, Maricourt draw a line on the lodestone round. After repeating the operation on other parts of the magnet and when it has drawn a good number of them on its surface, the pattern shown is that prove circles completely analogous to the ground and cut into two extreme points of the magnet. Surprised by analogy with the Globe, called poles Maricourt calls these two particular points of the magnet, north pole and south pole. In subsequent experiments found that the way that magnets attract each other is determined only by the position of its poles, as if these constituted the seat of what was thought at the time was the magnetic power. These concepts will play an important role in the development of theories of polarization later.

Conclusions: We are delighted to work these last because we learned new things, like, what can make ra magnetite.
