How do scientists know magnetic reversal happens?
The "original" (the one that existed at the time the rock solidified) field is stored in some rocks.
Who said the magnetic field theory?
Tesla was a very important scientist and he said the magnetic field theory. It was a very significant theory and today we all know about the magnetic fields. A pop band has also used this name too.
What are three characteristics of magnetic reversals?
In the past, the polarity of the Earth's magnetic field has reversed, many times over. This was discovered in samples of the rocks of the ocean floor at mid-ocean ridges, where matching patterns of magnetic polarity were discovered on each side of the mid ocean ridge. It is believed that the magnetic field is caused by electrical currents in the Earth's interior. [We know that the interior is too hot to sustain the magnetism of a bar magnet. As proved by the Curie's.] If these currents circulate parallel to the equator, then they would be pretty stable. but we know that the poles are moving. This may indicate that the path of electrical conduction is not a simple circle. We just have to wait. The earth's magnetic field is caused by the effect of the Earth's rotation on the liquid iron core. This field occasionally flips so that the direction that was magnetic north becomes magnetic south and what was magnetic south becomes magnetic north. This is called a magnetic reversal and these reversals can be detected in Earth's lava rocks which lock in the direction of the current field when they cool and solidify. Earth's magnetic field flips about once every 100 thousand years. The Sun goes through similar magnetic reversal cycles but on the Sun the reversals happen about once every 11 years.

The region of magnetic force around a magnet is know as it's?
Magnetic field
Which type of materials are magnetic?
i do not know. that is why i told you

Scientist know that the moon does not have a magnetic fieldthis probably means that the moon does not have?
movement in its core.
What do scientist not know about earths magnetic field?
When the north pole becomes the south pole.
What Is The Difference Between Magnetic reversal reversed field and normal field?
A magnetic reversal happens in a magnetic field generated naturally in a spinning object such as the Earth or the Sun. In cases where the magnetic field is generated as a result of spin the polarity of the field (where the north and south poles are) flips on a regular periodic basis. For instance about once every 11 years on the Sun and about every 100 thousand years on the Earth. This flipping of the field is called a 'magnetic reversal' on Earth and a solar cycle on the Sun. Between flipping events the magnetic field of the body is regular or normal (but of cause in the opposite orientation each flip) but during the flipping process the field is chaotic with many minor polar regions appearing round the body (as sunspots during a solar maxima) and presumable a similar but slower thing happens on Earth (we do not know yet but it looks as though the Earth's poles may be beginning to reverse at the moment).

How do scientist know the measuremnt of the earth mantle and core?
Because of the difference/wavering in the earths magnetic field due to thwe fact the inner core is largely Iron....
What are the causes of magnetic drift?
I want to know about magnetic drifs.what are the causes? I want to know about magnetic drifs.what are the causes?
How do scientist know that magnetic field originate from north always?
There are two kinds of magnetic poles. It is just a matter of convention that we *define* one of the north. Then we *define* the direction of the magnetic field to be the direction of force experienced by a test north pole. Magnetic field lines and their directions don't really exist, they can only be observed indirectly. It follows from our definition that they must originate in the north poles.

wanted to know if this insurance cover tubal reversal surgery?
I do not think any of them do
Region around a magnet in which magnetic force can act?
Magnetic freild
How did exploration contribute to the scientific revolution?
exploration would have helped in many ways for example look at the arctic that is how scientist know about global warming plus magnetic fields after that their are many other things that help look at geographers their job is to understand the landscape that later can help many scientist
