For the planet : none.
For the planet as we know it:
it shields us from the solar wind, a flow of high energy particles that the sun emits (solar flares,ect.) ,much as the ozone layer protects us from ultraviolet radiation.

∙ 9y agoThe Earth's magnetic field deflects the solar wind because it has charged particles that has harmful ultraviolet radiation. It keeps the atmosphere in place.

What would happen if the earth didn't have a magnetic field?
If we didn't have the earth's magnetic field, eventually all of the harmful and deadly rays from the sun would destroy life on earth.
What can the orientation of a rocks magnetic field can tell you?
The orientation of a rocks magnetic field can tell you it's relative age.
What if earth's magnetic field did not occasionally reverse polarity?
We expect Earth would still have a magnetic field during a reversal, but it would be weaker than normal with multiple magnetic poles. Radio communication would deteriorate, navigation by magnetic compass would be difficult and migratory animals might have problems. Many migratory animals use the geomagnetic field to orient themselves. However, even if Earth's magnetic field began a reversal, it would still take several thousand years to complete a reversal.
What would happen to people if the magnetic field was gone?
If the magnetic field disappeared, we'll be in danger of gamma rays like solar winds and cosmic rays because magnetic fields shields those things. Without the magnetic field, compasses will no longer work and we would need to find other ways to measure direction to navigate. Also, birds depend on the magnetic field for navigation during migration and would no longer be able to do that.
Earth's magnetic field affects?
effects of earth's magnetic field:-The sun emits huge amount of solid charged particles every time(called solar wind). if these particles are allowed to enter our earth, then there would be no chance of existence of life as this horrible effect of the solar wind would scrape away the atmosphere of our earth. but this magnetic field of our earth repels all these solid particles from the sun. by K.

How does Earths magnetic field benefit humans?
Earth's magnet field shields humans from dangerous radiation form the sun and protects the earth's atmosphere form the solar wind. Without the magnetic field, there would be no human life on earth.
What effects do Earths magnetic field and ozone layer have on Earth's ability to support life?

Why is earths magnetic field impotant?
The earth's magnetic field is important in that it prevents the sun's solar radiation from killing life on earth by wiping out the earth's atmosphere and deflecting dangerous radiation.
What is the half life of the earth's magnetic field?
Magnetic field doesnot have a half life. Elements have half life.
What is performed by earths magnetic fields?
Its main 'function' is to block most of the ultra violet radiation from the sun. Without the magnetic field - the UV radiation would be far too high to allow life to survive here.
How does the earths magnetic field help life to be sustained on earth?
the radiation charges or ionizes the air in the upper atmosphere. the charged air conducts and acts like a wire passing thru a magnetic field which shields the earth from other particles and rays look for Van Allen belts
The presence of a magnetic field indicates that a planet may have what?
A magnetic field indicates a ferrous core. This is necessary for life to begin because a magnetic field is needed to deflect solar radiation.
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 kind of destruction would happen if the earths core stopped rotating?
it wil cancel the magnetic field whch will cause radiation from the sun to penitrate and kill off life on earth
How does earth magnetic field protect life on earth?
The earth's magnetic field protects the surface from getting struck by solar radiation.
If the magnetic poles were going to switch on your planet would you know it was going to happen?
The compass needle is then showing to the opposite direction. However not only will this confuse explorers, but birds and animals to. Some animals navigate using the earths magnetic field. BUT you may think life will just die, it won't. Animals and life and survived before so there is no reason it wont. Also the only problem is that it could mess up the magnetic field, and stop the earths magnetic field blocking the suns harmful rays. Many people mistakenly think that the magnetic field protects the surface from cosmic rays, but it is mostly the atmosphere that does that. When the field switches, the magnetic field gets very low, and intense cosmic rays reach the top of the atmosphere (instead of being deflected by the magnetism), but only a few percent increase is measured at the Earth's surface. (At the North Magnetic Pole there is never any shielding, and that is how much stronger the surface cosmic rays are.) Some birds and protozoa that use the magnetic field for navigation would be disoriented. And our compasses would be useless until the field settled down in its reverse direction. The last recorded switch was about 790,000 years ago.
How does the earths magnetic field influence us on earth?
Directly : not at all. BUT It deflects the solar wind, thus the radiation levels on the Earth's surface is compatible with life; and there's still enough air for us to breath.
