Can earth loose atmosphere when magnetic field changes?
Earth's magnetic field is weaking such as it did on Mars, so are we also going to loose our own atmosphere as mars did?
What is the layer in which the magnetic field of the Earth is produced?
The outer liquid core produces the strong magnetic field of the Earth, through the dynamo effect.
Does earth's magnetic field cause gravity?
No, Earth's magnetic field does not cause gravity because there are two different types of forces.
Would an asteroid fragment generate a magnetic field when entering the earth's atmosphere?
Yes, it generate a magnetic field when it enters into the earth atmosphere.
Describe how the polarity of earth's magnetic field is recorded in the sea-floor?
The polarity of the Earth's magnetic field is recorded in igneous rocks, and reversals.
What has its own magnetic field?
Planet Earth
Is earth has its own electric field?
Earth has its own magnetic field which is emitted from iron core. This protects us from harmful rays. But it does not have an electric field
Plants with a magnetic force?
Compass plants respond to Earth's magnetic field, but do not produce their own magnetic force.
Can earth loose atmosphere when magnetic field changes?
Earth's magnetic field is weaking such as it did on Mars, so are we also going to loose our own atmosphere as mars did?
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 is resion of Earth magnetic field?
The Earth's magnetic field is the result of electrical currents flowing in the earth.
What magnetic fild do you detect when you go hiking?
You don't but your compass does: it's the Earth's own magnetic field's polarity and direction.
Why does a compass point North?
The magnetized needle of a compass is attracted to the Earth's own magnetic field which has magnetic poles at the North and South.
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.
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.
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.
