Deep below the surface of the Earth is the liquid outer core of the planet. This core is composed mostly nickel and iron and rotates independently of the rest of the planet. This spinning ball of iron creates the Earth's magnetic field....

What creates the magnetic field in an electromagnet? What do magnetic field lines represent? What are the characteristics of a magnetic field? What is Earth's magnetic field made of? How strong is a magnetic field? What are magnetic field lines made of?
Researchers have shed light on how heat is conducted by the inner and outer cores of the Earth to create its protective magnetic field. AsianScientist (Jun. 16, 2016)– Earth’s magnetic field shields us from deadly cosmic radiation. Without it, life as we know it could not exist. But ...

these electric currents, in turn, creates Earth’s magnetic field.A molten core that generates a magnetic field is a dynamo, and the action of this dynamo magnetizes life on Earth.But, the moon doesn’t have a magnetic field now, and scientists have long believed that it has never had ...
In summary, Earth’s magnetic field is not just a cosmic oddity; it’s a fundamental aspect of our planet’s ability to support life. It acts as a shield and a guardian, playing a vital role in maintaining the conditions necessary for life to thrive on Earth. ...
How would the extreme conditions inside a Super-Earth affect its habitability? "The interior dynamics of our planet are crucial for maintaining a surface environment where life can thrive—driving the geodynamo that creates our magnetic field and shaping the composition of our atmosphere," explained...
