The field is generated by earth's large iron core.
What else can I help you with?
What is the major cause of earths magnetic feild?
Earth's liqid metal Inner Core passes through a magnetic field causing the liquid metal to electomagnetically charge the planet.
Could a magnetic field anomaly cause a major bird kill?
It won't be possible to answer that until somebody explains what in the world a "magnetic field anomaly" is.
What 1 major difference between bar magnets and electroagets.?
Electromagnets only have a magnetic field when electrical current if flowing through them. When the power if off, so is the magnetic field. A bar magnet ALWAYS has a magnetic field.
What is a major cause of erosion on earths surface?
one major contributor is moving water
Two major fields of natural science?
1. gravity 2. magnetic field
What is the major process that is thought to produce the Earth's magnetic field?
The convection in the outer core, along with rotation of Earth that causes rotation of the outer core, initiates a flow of electric current in the core. This flow of current within the core produces and sustains Earth's magnetic field.
Can a solar flare destroy your earts magnetic field?
If you mean the Earth's magnetic field then no. It could disrupt it temporarily and cause problems but as the Earth's magnetic field is thought to be generated by the molten iron core of the Earth, a solar flare wouldn't be able to permanently destroy the field.answ2. Please ignore any suggestion that the nickel - iron core of the Earth has anything to do with the Earth's magnetism. The inner core probably has a temp of around 5700 deg, (the temp of the Sun's surface!) hugely in excess of the Curie Point of iron!The earths magnetic field is generated by electrical currents in the magma, running roughly parallel to the equator. There may be several such currents, and we see the net effect.The solar wind ordinarily contributes a few % of the magnetic field. But in a solar storm, could easily reverse it for a period. Hopefully to revert to that of magmatic origin.Solar storms have in the past destroyed power grids, and telephone systems. GPS would be unreliable during a major event.
What effects does the core have on the earth's climate?
Since the earth's core produces a magnetic field, it has a major effect on the climate. The magnetic field keeps the dangerous rays of the sun away from the earth making it much more habitable by all creatures.
Is the earth's magnetic field always the same?
The earth's magnetic field is present because of the molten iron in its core. Always a little change keeps on occurring in the earth's magnetic field. Although the change is very little with respect to time,but it is considered one of the major factors for the end of this world.
What is electromagnetic induction?
Electromagnetic Induction mainly deals with the ways that energy is shifted about between Electric and Magnetic fields in various circumstances. Here are some major examples:1. A moving Electric Current Induces a Magnetic field: Electromagnets.2. A moving conductor in a magnetic field Induces an Electric Current: The Dynamo or Electric generator.3. An Electrified Conductor in a Magnetic field Induces motion in the Conductor: The Electric Motor.Related Information:Albert Einstein's considerations of inductance, an Electrified length of conductor moving through a Magnetic Field in an empty volume of space, led him to his theory of Special Relativity.
What are two things that protect the earth from the sun?
The ozone layer absorbs most of the sun's harmful UV radiation, protecting the Earth's surface from its damaging effects. Earth's magnetic field also plays a role in shielding the planet from the solar wind and dangerous charged particles emitted by the sun.
What are the consequences of a shift of the magnetic poles?
While the poles are shifting, the Earth would have no shield against harmful gamma rays,and as a result all life would end.I think you are getting a little mixed up. Nothing like mass extinction will happen with Magnetic Polar Shift.Now if you were talking about Geographic Polar Shift, then most probably, because of something catastrophic happening to knock the Earth's Axis of Rotation out of line, would cause mass extinction.
