The history of the development of electricity

1. Amber and magnets in BC There was a philosopher named Thales among the Seven Sages of Ancient Greece.

Around 600 BC, Thales saw the phenomenon that the Greeks at that time attracted feathers by rubbing amber, and magnetite to attract iron pieces, and thought about the reason. His explanation is said to be: "Everything has a spirit.

Magnetic attracts iron, so magnetism has a spirit. "The "magnetism" mentioned here is magnetite.

The Greeks called amber "elektron" (homonym with English "electricity"). In the East, according to the book "Lv's Spring and Autumn Period", China has used magnets to make compasses in the Warring States Period, and they used the magnetic needle of the compass to identify the direction in ancient times.

1. Magnetism and static electricity Commonly referred to as triboelectric electrification, people only knew it as a phenomenon in BC. For a long time, the understanding of this phenomenon has not progressed.

The compass has been used in navigation since the 13th century. At that time, the compass was made of needle-shaped magnetite and placed in straw, so that it could float on the water.

In the early 14th century, a nautical compass with a magnetic needle suspended by a rope was made. This compass played an important role in Columbus' discovery of the Americas in 1492 and Magellan's discovery of a route around the earth in 1519.
