How have switches in the location of earths magnetic poles been determined?

∙ 11y ago
Magnetism leaves particles in molten metals lined up with north and south poles (magnetic poles, not the Earth's poles). Over time different layers of rock show that the N-S and S-N poles have switched, with S pointing in one direction and S pointing in a different direction depending on the age of the rock.

Which location is earths magnetic field is the strongest?
The equator
At which location is earths magnetic field the strongest?
2
What is earths magnetic field called?
It is Earths' "Magnetosphere".
How is the orientation of Earth's magnetism recorded in rocks on the ocean floor?
Earths magnetic orientation is locked into the rock when the rock cools
In which direction we should sleep and why?
this article is incorrect about earths magnetic effect on the body. Studies show that the body is south magnetic interior and north magnetic exterior in the daytime and this switches at night. It is this switch to inner north that stimulates the secretion of melatonin which puts us to sleep. so head facing north is the best for sleep. But I find everyone is different. and the earths magnetic field has been weakening for some time and is very low so not having its full effect.
Which location is earths magnetic field is the strongest?
The equator
At which location is earths magnetic field the strongest?
2
How much sunlight reaches a location at a particular time is determined by earths shape and what?
the earths shape and its rotation
The possible source of earths magnetic core is?
The molten iron and medals inside the earths core are the reasons for the earths magnetic core.
What is earths magnetic field called?

Is Lanthanum magnetic?
which of the list of rare earths are magnetic
How is earths magnetic field used by people and animals?
the earths magnetic signature is a negative polarity signature
Is earths core a source of earths magnetic field?
Yes.
Earth's magnetic field results from the spinning of the?
The earths magnetic field results from deep in the earths core. Magnetic conduction from within the earths core is believed to be the cause of this.
