1) A lodestone (a magnet) held on a string (or, ubiquitously, in a compass) will swivel and orient itself to the earth's magnetic field. Iron particles in cooling magmas will align themselves similarly (aiding in analysis of plate-tectonic palaeogeography).
2) The earth is only capable of sustaining advanced life due to its magnetic field repulsing most of the harmful radiation in the solar wind. I.e., you're alive due to it.
3) Aurora are a visible manifestation of the interaction of solar radiation upon the earth's upper atmosphere as directed by its magnetic field.
What else can I help you with?
Evidences through which you get to know that earth has magnetic field?
A compass.
Does Uruguay have a magnetic field?
The earth as a single object has a magnetic field. If Uruguay is part of the earth, it shares the earth's magnetic field.
What causes Earth's magnetic field to have the shape it does?
As you might already know, a magnet is the most powerful at it's ends. So what the inner core of the Earth's magnetic field does is that it surround the Earth. Thank you.
What is resion of Earth magnetic field?
The Earth's magnetic field is the result of electrical currents flowing in the earth.
What creates the Earths magnetic field?
Scientists believe that it is the movements in the liquid outer core that create the magnetic field. Earth's magnetic field affects the whole planet.
Where the vertical component of earth's magnetic field is zero?
The vertical component of Earth's magnetic field is zero at the magnetic equator, where the magnetic field lines are horizontal. At the magnetic equator, the magnetic field lines run parallel to the Earth's surface, resulting in a zero vertical component.
What is the magnetic force of this planet called?
The magnetic force on Earth is called Earth's magnetic field or also the geomagnetic field.
Does the moon have a stronger magnetic field than the earth?
No, the moon does not have a global magnetic field like Earth. Some localized magnetic fields have been detected on the moon's surface, but they are much weaker than Earth's magnetic field.
Earth's magnetic field is believed to be generated from what region?
If you mean the region of influence of the earth's magnetic field then its called the earth's magnetosphere
Does the earth have a magnetc field?
Yes, the Earth has a magnetic field.
Which layer of the earth produces its magnetic field?
The earth's outer core produces the magnetic field.
What is the leading theory for what causes earth's magnetic field?
The Dynamo Theory it what causes Earth's Magnetic Field
