Earth magnetic field
What is the link between the earth magnetic field and End of life on earth?
What happen if the earth magnetic field changes?
What is earth magnetic field?
On 2016 February 17 ."japan aerospace exploration agency "sent a satellite named "hetomi" the aim of satellite is to observe the high energy sources like "supernova ,block holes" after launching 40th day on March 26th unfortunately communication has been stopped between satellite and space station .the satellite have 14 meters long .it have 5 divisions. before the day of communication fail's satellite changed his orbit and rotated itself without any control' the people thought that "satellite destroyed due to some internal failure .but the reality is not that internal failure around 50 satellites facing " mechanical and electrical failure's" reaching specific place .why it happened . let's see
Earth magnetic field starts from the earth core extended up to space around it. the earth magnetic field produce due to earth outer core iron melts and form magmatic lines around it ..
Earth magmatic field have two radiation belt's.
1 inner radiation belt
The inner radiation belt starts from the surface of earth 500km extended to space 3000km as shown in above image ..
2 outer radiation belt.
The outer radiation belt extended from 16000km to 25000km in space around the earth it consists of more number of electrons .
The use of earth magnetic field is to protect from the space dust, Astrid's, cyclones coming from sun...
If earth do not have strongest magmatic field then our earth become like Mars planet .
Due to some reactions in earth core every 2 to 3 crore years earth magmatic field changes .that means south pole and north pole become reverse.
The last magnetic field changed about 7,80,000 years
The time span of magnetic field change take place in 1000 to 10,000 years .
In 2013 the utopian space agency launched 3 swam satellites to study earth magnetic field the satellite observed Magmatic field capacity ,size and so on ..
The utopian environment agency researcher estimated that from past 3000 years earth magmatic field becoming week in up coming 1000 years starts reversing the magmatic poles.
Important news is from south America to South Africa region magmatic field becoming week this is called "south Atlantic anomaly" this have low earth orbit so when satellite reaching this radiation belt facing electronic failures this becoming great danger to Hubble telescope and international space station .when Hubble telescope reaching this anomaly not even one function working in it .when Hubble telescope move out of anomaly then functions start working.
During reversal of south and north poles navigation systems won't work .most electronic devices and power supply wires get damaged ,oxygen levels decreases , radiation increases , ozone layer get damaged, uv rays reach earth directly ,skin damage and mutation occur,60% of living kind will no longer to survive on earth .
We cannot stop the reversal of Earth magnetic field and also it is not happening in one day.
Scientists still confused to find solution for this.
Let's hope for the best thank you.
