It's actually not the magnetic field, which stop the atmosphere from leaking away, but the gravitational field. The reason for the atmosphere to stay is, that the earth provides a constant amount of force relative to the mass of earth. And there is less force pulling the atmosphere into space, and the atmosphere stays with most force, but if the force pulling the atmosphere into space increased, some of the atmosphere would leak, but the closer to the ground you get the stronger is the gravity, and that's why it would take A LOT of force to counter that of Earth.
Earth's magnetic field does not affect light or sound. It primarily interacts with charged particles such as electrons and protons in Earth's atmosphere and in space.
The earth's magnetic field is important in that it prevents the sun's solar radiation from killing life on earth by wiping out the earth's atmosphere and deflecting dangerous radiation.
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
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.
Earth's magnetic field is strongest at the magnetic North Pole and the magnetic South Pole.
