Studies of pottery made in the past 5000 years have helped reveal fluctuations in Earth's magnetic field over the past 300 years. The iron minerals in the pottery align with the Earth's magnetic field at the time of firing, providing a historical record of magnetic field strength and direction. This data has contributed to our understanding of how the Earth's magnetic field has changed over time.
Ancient pottery reveal magnetic field changes from long ago. By studying the alignment of magnetic minerals in the pottery, researchers can reconstruct past magnetic field intensity and direction, providing insights into the Earth's magnetic field history.
It is Earths' "Magnetosphere".
Earth's magnetic field is strongest at the magnetic North Pole and the magnetic South Pole.
The strength of Earth's magnetic field is strongest at the magnetic poles, which are not necessarily aligned with the geographic poles. The magnetic field is weakest at the magnetic equator.
When convection occurs in Earth's outer core, it generates electric currents due to the movement of the molten iron and nickel. These electric currents create a magnetic field around the planet, known as the Earth's magnetic field. This magnetic field plays a crucial role in protecting Earth from solar winds and cosmic rays.
Ancient pottery shows movement of the earth's magnetic field. Firing the pottery fixes the ambient magnetic field in the fired pottery.
People use Earth's magnetic field for navigation, such as in compasses to find direction. Animals, like birds and fish, can sense Earth's magnetic field to navigate during migration or find their way in the ocean.

Yes.
It is made by the movement of the earths core and magma field
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.
because it has the hydro electric power to control the earths magnetic field
Yes, the magnetic field of the earth has flipped. The evidence is in fired pottery in historical times.
It is Earths' "Magnetosphere".
earths magnetic field is generated by the circulation of liquid metal.
It is Earths' "Magnetosphere".
The Earth's magnetic field was roughly 8 times stronger in 800 B.C. compared to today. This estimate is based on historical data from measurements of ancient pottery using a technique known as archaeomagnetism.
