WebIf the words north and south remind you of anything, the earth is in fact a giant magnet. A compass is a tiny magnet balanced on a point so it can turn freely. The magnet is attracted by the earth’s magnetic north pole and always points in that direction. A good way to see how the magnet attracts is to do the following experiment.

WebApr 27, 2012 · 24. The simplest theory on the origin of the earth’s magnetism is that the center of the earth is one huge permanent magnet made of iron and nickel. Earth’s core consists mainly of these two mainly materials, these theory seems acceptable at first. Laboratory studies show that iron loses its magnetism at 770°C and nickel at 358°C. 25. WebAn experimental study of the rotational magnetocaloric effect in Ni(en)(H2O)4SO4∙2H2O (en = ethylenediamine) single crystal is presented. The study was carried out at temperatures above 2 K and was associated with adiabatic crystal rotation between the easy plane and hard axis in magnetic fields up to 7 T.
