WebAug 3, 2024 · Generated by the motion of molten iron in Earth’s core, the magnetic field protects our planet from cosmic radiation and from the charged particles emitted by our … Web6500K. how do we know the earth has a liquid core? P waves pass through it, but S waves do not. Currents in the earth's molten iron core create the planets magnetic field. these current are probably caused by. rotational motion and convection. the shifting of large blocks of the earth's surface is usually referred to today as what ?

NASA Is Tracking a Dent in Earth

WebThe magnetic dipole moment of the Earth is approximately 8.0.1022 A m2. The source of the Earth's magnetic field is not known; one possibility might be the circulation of ions in the Earth's molten outer core. Assume that the circulating ions move a circular loop of radius 2515 km. What "current" must they produce to yield the observed magnetic ... WebApr 9, 2024 · How the Earth's Core Generates a Magnetic Field: The Earth's outer core is in a state of turbulent convection as the result of radioactive heating and chemical differentiation. The flowing molten metal in Earth's core creates an electric current and a magnetic field, which are amplified and sustained by the dynamo effect. green citrus aphid

The Moon may play a major role in maintaining Earth

WebJan 5, 2012 · Molten iron moving in Earth’s core generates the planet’s magnetic field, which protects the planet against solar flares and other space weather. The strength of Earth’s magnetic field is known to fluctuate on very long time scales; on rare occasions, the field has even reversed polarity, in which the magnetic north pole and magnetic ... WebMagnetic fields surround electric currents, so we surmise that circulating electic currents in the Earth's molten metalic core are the origin of the magnetic field.A current loop gives a field similar to that of the earth. The magnetic field magnitude measured at the surface of the Earth is about half a Gauss and dips toward the Earth in the northern hemisphere. WebThe center of the Earth is made up of two layers, the outer core and the inner core. The outer core is the third layer of the Earth. It is the only liquid layer, and is mainly made up of the metals iron and nickel, as well as small amounts of other substances. The outer core is responsible for Earth’s magnetic field.As Earth spins on its axis, the iron inside the … flow of water through an orifice
