• By the 11th century the Chinese had learned that a magnetic needle points north-south. • By the 12th century the European records mention the compass. • That there was a difference between magnetic north and the direction of the compass needle (declination) was known by the 16th century. • William Gilbert (1600) realized that the field was dipolar. • In 1698 Edmund Halley organized the first scientific expedition to map the field in the Atlantic Ocean.
The Plasma State • A plasma is an electrically neutral ionized gas. – The Sun is a plasma – The space between the Sun and the Earth is “filled” with a plasma. – The Earth is surrounded by a plasma. – A stroke of lightning forms a plasma – Over 99% of the Universe is a plasma. • Although neutral a plasma is composed of charged particles- electric and magnetic forces are critical for understanding plasmas.
