How is Earth's electromagnetic field generated and what role does it play for all living organisms? What would happen if it doesn't exist? Explain.

Explanation:

Earth's magnetic field is generated by interactions in its molten outer core. As the flowing iron generates electric currents, the electromagnetic field is constantly changing.

The electromagnetic  fields surround the entire planet and act as protective shields blocking out the harmful effects of solar radiation, cosmic rays, sand, and other forms of space weather.

If it did not exist then :-

THE COMPASSES WOULD DO WIERD THINGS.THE AURORA WOULD'NT BE THE SAME.COSMIC RAYS COULD NOT REACH THE SURFACE.WIDESPREAD POWER OUTAGES AND BROKEN SATELLITES.OUR ATMOSPHERE COULD BE STRIPPED AWAY.BIRDS COULD NOT MIGRATE FOR WINTER.
