Magnetometer
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.
earths magnetic field is generated by the circulation of liquid metal.
Scientists believe that it is the movements in the liquid outer core that create the magnetic field. Earth's magnetic field affects the whole planet.
About 41,000 years ago.
It's called the Dip.
seismoggraph
Yes.
It is made by the movement of the earths core and magma field
A compass is an instrument containing a freely suspended magnetic element which displays the direction of the horizontal component of the Earth's magnetic field at the point of observation.
When lava cools and solidifies, magnetic minerals within it align themselves with Earth's magnetic field. By studying the orientation of these minerals in lava layers, scientists can track changes in the Earth's magnetic field over time. Reversals of the Earth's magnetic field are reflected in lava layers as bands of alternating magnetic orientation.
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
It is Earths' "Magnetosphere".
earths magnetic field is generated by the circulation of liquid metal.
It is Earths' "Magnetosphere".
= An effect of the magnetic field is "Van Allen radiation belt" =
The Earth's Magnetic field.
