What is a good sentence for magnetic reversal?
The sun goes through a magnetic reversal twice in every sunspot cycle.
The weak magnetic field around mercury suggests what?
upcoming magnetic reversal
What is the estimated time for a magnetic reversal to occur?
In the sun, the cycle corresponds with the cycle of visible sunspot numbers, and is roughly 11 years. In the Earth, the cycle of magnetic reversal appeares to be very irregular, with periods anywhere between 200,000 and 400,000 years. In both cases, the reversal is not something that happens suddenly at, say, 11:36 one morning. It happens gradually and continuously. For something to compare it to, think of a wave on the lakeshore ... Is the wave in, or is it out ? It's changing smoothly between the two extremes. Similarly, both the sun and the Earth are in the process of magnetic reversal right now.
What happens in a magnetic reversal?
The Earth's magnetic polarity reverses. On effect is that remnant magnetism induced in igneous rocks stays, recording the change, and these have been measured to analyse the effect.
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 was the theory that was shown to be correct by age evidence and magnetic clues?
Magnetic Reversal
What is a sentence for magnetic reversal?
The sun goes through a magnetic reversal twice in every sunspot cycle.
What is a good sentence for magnetic reversal?

What is it called when rocks are different because Earths magnetic poles change places?
Magnetic Reversal. Several magnetic reversals have occurred over geologic time.
What is the process by which Earth's magnetic poles change places?
Magnetic reversal
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.
The switch in direction of earth's magnetic north and south poles?
Magnetic Reversal
Switch in direction of earths magnetic north and south poles?
Magnetic Reversal
The weak magnetic field around mercury suggests what?
upcoming magnetic reversal
How can we tell a magnetic reversal has taken place?
opposite
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."
Which best describes search north magnetic pole?
In our solar system has magnetic pole reversal
