What else can I help you with?
Earth is what kind of magnet?
Its an electro-magnet - currents flowing through the iron core.
How long does it take for the Earth's magnetic field to reverse?
The Earth's magnetic field can take thousands of years to reverse.
How does earth's magnetic field affect the compass?
Earth's magnetic field is what allows a compass to align itself with the magnetic poles, causing the needle to point north. The magnetic field provides a reference point for navigation, helping people determine their direction relative to the Earth's magnetic field. Any changes or disturbances in the magnetic field can affect the accuracy of a compass reading.
What is the Total magnetic field of the earth?
The total magnetic field of the Earth is approximately 25 to 65 microteslas. This field is a combination of the main magnetic field generated by the Earth's core and the smaller contributions from various external sources such as the ionosphere and magnetized rocks in the crust. The strength and direction of the Earth's magnetic field are continuously changing due to geophysical processes.
Can earth loose atmosphere when magnetic field changes?
Yes, Earth's atmosphere can be affected by changes in the magnetic field. A weakening of the magnetic field could potentially make Earth more vulnerable to solar winds, which can lead to loss of atmospheric gases over time. However, Earth's atmosphere is held in place by gravity as well, so any loss would likely occur over millions of years and not immediately.
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.
Earth is what kind of magnet?
Its an electro-magnet - currents flowing through the iron core.
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.
How does the presence of iron in nature contribute to the formation of magnetic fields?
Iron is a key element in the Earth's core and its presence helps create the planet's magnetic field. When iron-rich materials heat up and cool down, they align in the direction of the Earth's magnetic field, creating a magnetic field of their own. This process is known as the geodynamo theory and is responsible for generating the Earth's magnetic field.
Is the moon not magnetic electromagnet or permnanetmagnet?
The moon does not generate its own magnetic field like Earth does. The moon is considered non-magnetic because it lacks a global magnetic field that is generated by a planetary dynamo.
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.
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.
Why does a compass point North?
A compass points north because of the Earth's magnetic field. The magnetic field exerts a force on the needle of a compass, aligning it with the magnetic north pole, which is close to the geographic North Pole.
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.
