What happens when the earth's magnetic field turn into 0?
If the Earth were to lose its magnetic field, things would get a lot more interesting. We'd get a lot more ionizing radiation at the surface, which would result in more mutations (and more deaths).
How could earths magnetic field magnetize an iron bar over years?
I see where you're going, and it is feasible, but any magnetic charges that develop in it would be veryextremely minute (meaning very little). But to answer your question, Earth can magnetize an iron bar because the poles in iron are scattered in different directions, and as it's just laying there, they naturally align with Earth's magnetic field. It's hard to explain, because magnetism is such an abstract force, but all I can say is that it naturally happens.
Why is the Earth's magnetic field important to life on Earth?
because this is used in magnetic compasses so we can find north and it helps with research abouyt things releted withg science and tecnology and even maths.
Why does the north pole of a magnet point towards the north pole of earth?
It is unclear how the earth developed its magnetic field. The Earth's magnetic field approximates a magnetic dipole. And we believe that dynamo action within the molten layers of iron and nickel around the solid core of the earth generates the field, but investigators have not been able to pin down what it was that initiated the field. Note that the magnetic field intensity of the Earth's magnetic field varies over time, becoming weaker and stronger. Also, the polarity of the Earth's magnetic field moves or migrates within the planet over time as well, and the polarity of the field has demonstrated a tendency to "switch" or "reverse" at intervals. This geomagnetic reversal is well documented by a number of investigators. Use the link below for more information.
How does the Earth's magnetic field help people?
The Earth's Magnetic shield is important for preventing the Atmosphere from being destroyed by solar wind by deflecting dangerous particles from impacting the Earth.It protects Us from the magnetic / electrical radiation that comes from the Sun. High radiation periods coincide with solar storms.It protects us from solar radiation (wind) from the sun
How do you get to the core of the earth?
you can't get to the earth's core it's to deep, you would melt from the lava, and if you did get to the core you would disrupt the earths magnetic field and we would be killed by a solar storm.
What does Earth's magnetic field protect us from and how?
the earths magnetic field is the only reason that were alive right now the reason being is the suns heat rays are very powerful and very hot if the magnetic field would be gone everything on earth would vanish into ashes.
What evidence is there on earth having a magnetic field?
To start if we didnt have a magnetic field we would be fried by the suns radiation. The northern lights are evidence that we have a magnetic field surrounding earth.
Would an asteroid fragment generate a magnetic field when entering the earth's atmosphere?
No, an asteroid fragment would not generate a magnetic field when entering Earth's atmosphere. Its passage through the atmosphere would likely generate heat and light due to friction with the air, but it would not create a magnetic field.
What are the two theories that attempt to explain earths magnetic field?
the two theories that attempt to explain earths magnetic field are Dynamo theory--the theory that is believed by the majority of geologists. it says the rotation of the earth causes the liquid core to move in one overall direction, causing the movement of electrical charges, creating the current making the magnetic field. Rapid-decay theory---is believed by the minority of geologists. it makes assumptions about how the earth was formed to calculate how much electrical current would be generated and how much it would have slowed down. =
What changes in cosmic ray intensity at earths surface would you expect during periods in which earths magnetic field passed through a zero phase while undergoing pole reversals?
Cosmic ray intensity at Earth's surface would be greater when Earth's magnetic field passed through a zero phase because magnetic shifting is minimal. Fossil evidence suggests that the periods of no protective magnetic field may have been as important in changing life forms as x-rays have been in the famous heredity studies of fruit flies.
What if earths magnetic field was fixed in place and the polarity didn't reverse what effect would this have on our observations of seafloor basalts?
If Earth's magnetic field was fixed without reversals, newly-formed seafloor basalts would only show one magnetic orientation. This uniformity would make it harder to track the movement of tectonic plates or determine the age of the seafloor using magnetic stripes. It would also impact our understanding of plate tectonics and Earth's geology.
How does Earths magnetic field benefit humans?
Earth's magnetic field acts as a shield, protecting us from harmful solar radiation and cosmic rays. It also plays a crucial role in animal navigation and migration, including some species of birds and sea turtles.
Why would the earth cease to exist without the earths magnetic field?
There are certain high-energy particles electrically charged particles that are emitted from the sun and travel toward our planet. These particles are called Cosmic Rays. If they were allowed to strike the earth, they would kill all life on the planet. However, the earth's magnetic field deflects the vast majority of these particles, keeping them from hitting the planet. If the magnetic field was too small, it would not deflect enough of these Cosmic Rays. If the field was too strong, it would deflect the cosmic rays, but it would cause a deadly magnetic storm that would make life impossible!
What would happened if the magnetic field of the earth inverse?
Nothing.
What would happen to electronics magnets etc if the earths magnetic poles changed?
Nothing - The polarity of an electromagnet depends on the direction of current flow and you can effect the same change in orientation to the earth's field by moving the electromagnet rather than the earth's field.
Does the earth rotation effect the sun in any way?
If there is any effect at all, it would need to be a very tiny one. The only way that the Earth's rotation might affect the Sun would be in the way the Earth's rotation generates Earth's magnetic field. Our magnetic field affects the way that coronal mass ejections, huge bubbles of ionized gas from the Sun, behave when they get close. But the Sun has a magnetic field of its own, much stronger than the Earth's field, and it is unlikely that the Earth's magnetic field would affect the Sun or the Sun's magnetic field in more than a minuscule fashion.
