Earth's magnetic field

Ages

Introduction

Summary

The Earth is a magnetized planet. The Earth's magnetic field is like that produced by a large bar magnet. The south magnetic pole coincides with the north geographic pole.

Note how a compass remains tangential to the field lines at every point.

Goals

• To view the geometry of the Earth's magnetic field.
  
• To show that the compass remains parallel to the field lines at every point.
• To distinguish geographic poles and magnetic poles.
