What do scientist not know about earths magnetic field?
When the north pole becomes the south pole.
British scientist who discovered that a changing magnetic field produces an electric current?
faraday
Does lightning produces magnetic field?
Yes, The movement of electrical charges produces a magnetic field
Which layer of the earth produces its magnetic field?
The earth's outer core produces the magnetic field.
Is earths core a source of earths magnetic field?
Yes.
How are the Earths magnetic field made?
It is made by the movement of the earths core and magma field
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.
Why do scientists believe that the inner core is the source of earths magnetic field?
because it has the hydro electric power to control the earths magnetic field
What do scientists think produces earths magnetic field?
Scientists think that Earth's magnetic field is generated by the movement of molten iron and nickel in the outer core of the planet. This motion creates electric currents, which in turn generate the magnetic field that surrounds the Earth.
What is earths magnetic field called?
It is Earths' "Magnetosphere".
What is an electrical current that produces a magnetic field?
The deflection of a magnetic compass in the presence of an electric current, is evidence that an electric current produces a magnetic field.
Where does the earth's magnetic field get its power from?
earths magnetic field is generated by the circulation of liquid metal.
