EARTHS MAGNETIC FIELD

All about the “E.M.F”

What is the E.M.F?What is the E.M.F?

It’s a shield that helps protect the earth from:Violent solar storms Space particles

But when it fails to protect us, the solar winds can seriously affect disrupt or destroy our satellites

Is it dangerous that our satellites might be destroyed?

How does it work?How does it work?

• The magnetism of the field is generated by the rotating lava in the Earth’s core – Because the Earth’s core has iron and nickel in

it the rotation generates an electric charge– The heat of the core is another element that

contributes to the charge

Earth is just a big magnet

• The magnetic field divides into the North and South pole– The connecting field

lines is called the “magnetosphere”

• ITS HOW A COMPASS WORKS! When a compass reads

North its repelling the magnetic north
