What properties of iron bearing minerals on the seafloor support the theory of seafloor spreading?
iron bearing minerals can record Earth's magnetic field direction. when Earth's magnetic field reverses, newly formed iron bearing minerals will record the magnetic reversal. magnetic reversals show new rock being formed at mid-ocean ridges. This helped explain how the crust could move
What is the neutral point of the magnetic field?
In a combined magnetic field, a neutral point is a place where the magnetic field is zero
Can things hover in a magnetic field?
Things that are affected by a magnetic field, such as iron and steel can hover in a magnetic field.
What are the earth polar shifts?
A geomagnetic reversal is a change in the orientation of Earth's magnetic field such that the positions of magnetic north and magnetic south become interchanged. These events often involve an extended decline in field strength followed by a rapid recovery after the new orientation has been established. These events occur on a scale of tens of thousands of years or longer.more info herehttp://en.wikipedia.org/wiki/Geomagnetic_reversal
What is a magnetic field will be produced at some point in space if the electric field at the point?
As far as the electric field is stationary then no magnetic field. But when electric field is moving at a uniform speed then a magnetic field will be produced. This is what we call Lorentz magnetic field.
The weak magnetic field around mercury suggests what?
upcoming magnetic reversal
When was the most recent reversal of the earth's magnetic field?
As stated in Wikipedia: "The last reversal was theBrunhes-Matuyama reversal approximately 780,000 years ago."
How many year marks the reversal of the sun's magnetic field?
11 years.
When the Earth's polarity is reversed is the Coriolis effect also reversed?
No. The reversal of polarity is a reversal of Earth's magnetic poles. The Corilolis effect is a direct consequence of Earth's rotation and is not affected by the magnetic field.
What is the difference between magnetic reversal reversal field and normal field?
If you are a student reading Glencoe Science: Earth Science and you are taking the Chapter 17 Assessment...stop cheating and do the actual work morons.
What would happen if Earth's magnetism get reversed?
There would be a temporary weakening of the magnetic field during the reversal. After the reversal the only noticeable difference would be that compasses now point south instead of north. Navigation systems that use the magnetic field would need to be recalibrated.
What is happening to earths magnetic field?
In early 2014, scientists have discovered that the Earth's magnetic field has been weakening for some time. This could eventually lead to the switching of the Earth's magnetic poles.
What does a rapid change of a magnetic field induce?
It does not have to be positive or negative either one will produce reversal of the voltage applied by a factor
What is the magnetic field of Venus's?
Venus has a small magnetic field created by the interaction of its ionosphere and the solar wind. This is different from most of the intrinsic planetary magnetic fields (those generated by planetary cores) that are commonly spoken about. Venus either lacks an intrinsic magnetic field or it has one that is in the midst of a polarity reversal.
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 scientists know magnetic reversal happens?
The "original" (the one that existed at the time the rock solidified) field is stored in some rocks.
Which aspect of magnetic reversal provides evidence of continental drift?
Periodically, the magnetic field of the earth reverses polarity. The direction of the magnetic field is recorded in the magnetic properties of rocks when they are erupted. Rocks are being continuously added at sea floor spreading regions, and thus the magnetic reversals are recorded as pairs of parallel 'stripes' alongside the mid ocean spreading ridge.
