Earth as a Magnet

Earth as a Magnet

• The needle of a compass always points north because the needle is magnetized
• A magnetic pole is where the magnet exerts the most force.
• The magnetosphere is Earth's magnetic field.
• The north geographic pole is located at 90 degrees north.

Slide 2

• Earth's magnetic poles are NOT the same as the geographic poles
• Earth is like a bar magnet = both have magnetic poles and exerts a magnetic field
• The magnetosphere is strongest at poles
• Earth's north magnetic pole is located at about 80 degrees north
