Why Materials Magnetize:

Earth’s Magnetic Field:

The earths magnetic Field is crated by…..

Magnetic Declination: difference between true north “Geographic North” and the magnetic south

Progression of the earths magnetic Field  Scientists have long known that the magnetic pole moves. James Ross located the pole for the first time in 1831 after an exhausting arctic journey during which his ship got stuck in the ice for four years. No one returned until the next century. In 1904, Roald Amundsen found the pole again and discovered that it had moved--at least 50 km since the days of Ross.
