Has the magnetic field of the ever flipped?
Yes, the magnetic field of the earth has flipped. The evidence is in fired pottery in historical times.
Has earths magnetic field ever moved or changed?
Yes. The Earth's magnetic field changes and has flipped in historical times. Velikovsky noticed this in examining the magnetic oruientation of ancient pottery.
Does the earth's magnetic field ever chage positions?
Yes- in the distant geologic past it has flipped several times, as shown by the orientation of metallic minerals in rock that formed at those times, especially that of the seafloor.
Can a changing magnetic field produce a steady electric field?
Not a steady but a moving electric field can be produced by ever changing magnetic field.
When does the north pole become the south pole and the south pole become the north pole?
Answer The answer is no, of course not! It is the magnetic polarity of the earth that is being flipped, not the locations of Magnetic North and Magnetic South. Remember, 'Magnetic North' and 'Magnetic South' are locations, not magnetic poles. So even if their magnetic polarities flip, the names of the locations won't ever change! All that would happen is that the magnetic field would reverse, and your compass would point to Magnetic South instead of Magnetic North.Think of it this way, if the magnetic polarity of the earth flips, you wouldn't swap the names 'Arctic' and 'Antarctic'! So, why would you swap the names 'Magnetic North' and 'Magnetic South'!!!!!
Do magnetic field lines ever intersect?
yes
Has the magnetic field of the earth ever flipped?
There has been a lot of confusion about this. It depends if your asking about a geomagnetic reversal, or the other on. It has been forseen that there may be a geomagnetic reversal some time in the very near future, namely 2012. I think this is very true. See the Mayan callender which ends in 2012, in December. Apparently a geomagnetic polar shift will bring calamatity and death to earth,
What happens when a magnetic compass is held in space far away from earth's magnetic field....will it be influenced by the other stellar objects which may or may not have magnetic poles of their own?
How far away? Compasses function based on their interaction with the Earth's magnetic field. If a person were to take a compass outside of that field, it would cease to provide any relevant information. Of course, no human has ever been anywhere near that far away, but interplanetary robots and probes have.
What is the invisible force around a magnet called?
Have you ever seen a magnet? Did you see the field? There you go. While you can't see the field itself directly, you can see the effects of the field if you use iron filings or something like that; they'll line up with the magnetic field lines
What is belived to be responsible for the earth's magnetic field?
The earth's magnetic field arises from the core of the earth(that we know) but why? Have you ever heard of lodestones? Well they are naturally occurring magnets. They are basically composed of ferromagnetic materials like iron. Their magnetic property arises because the iron stays aligned with the magnetic field lines of the earth leading to a change in the arrangement of their electrons. But our discussion is for the origin of earth's magnetism. Well the core of the earth is composed of materials like Nickel and Iron, hence the core is sometimes called NiFe. Due to hot temperatures and pressure the electrons in the core are constantly changing positions and hence giving out a magnetic flux. The flux density is what gives the field.
Does magnetic field of earth causes some effect on humans?
Maybe it's a possibility, but no such effect has ever been detected or measured yet, and no component of human physiology has been identified that's sensitive to magnetic fields.
Will mars ever become Earth-like?
No. Analysis indicates that Mars was once more Earthlike than it is now. Then the magnetic field faded, allowing the solar wind to strip away most of its atmosphere.
