Magnetism of the Earth

1. MAGNETISM
OF THE
EARTH
PRESENTATION BY
SANJAY KRISHNA BHUYAN

2. o Why does Earth have a global or world-
wide magnetic field?
o Why should we care about Earth’s
magnetic field? What does it do for us?

8. SECULAR VARIATION

10. A LITTLE MORE..
The earth’s magnetic field isn’t strong
enough for us to feel, but many animals
can sense it and even use it to navigate.
It’s only about 0.4 Gauss, much weaker
than a small magnet you can hold in your
hand.
