Explanationव्याख्या
The Earth's magnetic field is generated by the Geodynamo Process.
This happens due to the convection currents of molten fluid iron and nickel in the outer core, driven by heat escaping from the inner core combined with the Coriolis effect from Earth's rotation.
पृथ्वी का चुंबकीय क्षेत्र 'जियोडायनेमो प्रक्रिया' (Geodynamo Process) द्वारा उत्पन्न होता है। ऐसा बाहरी कोर में पिघले हुए तरल लोहे और निकेल की संवहन धाराओं (convection currents) के कारण होता है, जो आंतरिक कोर से निकलने वाली गर्मी और पृथ्वी के घूमने से उत्पन्न कोरिओलिस प्रभाव के कारण गति करती हैं।
