Question

Actual reason of earth's magnetic field andatmospheric lightning

Answer 1

Solution :-

Magnetic field around planets behaves in the same way as a bar magnet. But at high temperatures, metals lose their magnetic properties. Earth's magnetic field is caused by a dynamo effect. The effect works in the same way as a dynamo light on a bicycle. Magnet is the dynamo start spinning when the bicycle is paddled, creating an electric current. The electric current is then used to turn on the lights. This process also works in reverse. If you have a rotating electric current, it will create a magnetic field. On Earth, flowing of liquid metal in the outer core of the planet generates electric current. The rotation of Earth on its axis causes these electric currents to form a magnetic field which extends around the planet.
