The spinning of these liquid metals produces the same effect as electric current in a coil which produces a magnetic field. Yes, that is true. Circulating ions of iron and nickel in a highly conducting liquid of Earth's core forms current loops and produces a magnetic field.

Oct 22, 2007· The word "ferrous" usually refers to materials that have a lot of iron in them. It's common for these materials to be strongly magnetic, but not all of them are. Different types of iron and steel are more or less magnetic. Highchromium stainless steel is nearly nonmagnetic, while pure iron tends to form magnets easily.

When a material is placed in a magnetic field H, a magnetization (magnetic moment per unit volume) M is induced in the material which is related to H by M = κH, where κ is called the volume susceptibility. Since H and M have the same dimensions, κ is dimensionless. m is the molar volume of the substance, M the molar mass, and ρ the mass density .

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 liquid outer core moves around.

The turbid mixture of cool sediments and hot liquid iron causes cooledoff, denser iron to sink back toward the inner core. The sinking iron would perturb the geodynamo's convection cells, causing frequent "excursions" of the dipolar magnetic field as measured at the surface.
