Elements of Earth's Magnetic Field:
- The magnitude and direction of the magnetic field of the earth at a place are completely given by certain quantities known as magnetic elements.
Explanation:
Earth has its own magnetic field whose poles are
- Magnetic North is in Geographical South pole.
- Magnetic South is in Geographical North Pole.
- A compass needle is a bar magnet with a pointed north pole. It is attracted to the magnetic south pole.
- Hence magnetic needle points in North Direction (Magnetic South).
