Web10 apr. 2024 · While the magnetic field is created largely by an ocean of superheated, swirling liquid iron in the planet’s outer core, other factors, like magnetised rocks in the crust and the flow of the ocean, also affect the field. We wouldn’t normally think of seawater as being a source of magnetism, but it does make a tiny contribution. WebThe Earth's magnetic field is generated in the fluid outer core by a self-exciting dynamo process. Electrical currents flowing in the slowly moving molten iron generate the magnetic field. In addition to sources in the Earth's core the magnetic field observable at the Earth's surface has sources in the crust and in the ionosphere and magnetosphere. how to save in picsart

The magnetic field of the Earth is generated by dynamo action in the liquid iron outer core (Labrosse, 2003). Dynamo action explains how a rotating, convecting, and electrically conducting fluid sustains a magnetic field. WebThe most feasible method by which the artificial magnetic field can be generated is through placement of hundreds (if not thousands) of magnet satellites into the orbit of the target moon or planet all of which revolve at certain distance and velocity.These kind of satellites may use solar energy as their main source of energy which in fact … north face jacket big and tall
