the outer core.
It is believed that there are currents of molten iron ore in Earth's interior, which cause this magnetism.
Earth's magnetic field is not in its crust. It passes through the crust, but it is generated by the differential motion of the inner and outer core. The core is mostly iron and nickel. This creates huge dynamo and generates our magnetosphere.
If the current is alternating, the magnetic field will also be alternating.
The Earths magnetic field is generated by the cores fluid metal rotating like a dynamo. The fields generated make an impressive electromagnet. We use it for navigation. The Aurora Borealis is caused when cosmic rays strike it. That aids our understanding of both cosmic radiation and the flux density of the field.
earths magnetic field is generated by the circulation of liquid metal.
the outer core.
If you mean the region of influence of the earth's magnetic field then its called the earth's magnetosphere
the crust
Earth's magnetic field.
The Earth's magnetic field is generated by the the Earth's spin and the fact that it has molten iron in its core. When convecting molten metals spin they generate electric currents and with these a magnetic field.
Venus does not have a magnetic field because its rotational period is very slow. This means that if its core had a liquid metal component, it would not be moving fast enough to generate a field.
It is believed that there are currents of molten iron ore in Earth's interior, which cause this magnetism.
Because it is far too small to have any effect. The Earth's magnetic field is thought to be generated thousands of miles underground by moving rivers of iron.
Yes. It has a modest magnetic field that is approximately aligned with the planet's axis of rotation. The field is a planetary dipole, and it is though to be generated in a manner similar to the way the earth is though to generate its magnetic field - dynamo action at or around the core. The strength of the field has been estimated as approximately 1% of Earth's. (see link)
