How does earth get its magnetic field
WebThere are two basic ways which we can arrange for charge to be in motion and generate a useful magnetic field: We make a current flow through a wire, for example by connecting it to a battery. As we increase the current (amount of charge in motion) the field … WebDec 9, 2024 · A bar magnet gets its magnetic field from ferromagnetism while Earth's magnetic field is due to the presence of electric currents in the core. Since the temperature of the core is so hot, the metal atoms are unable to hold on to their electrons and hence are in the form of ions. These ions and electrons are in motion in the core which forms ...

WebApr 19, 2024 · According to the currently accepted dynamo theory, earth’s magnetism is caused mostly by the rotating liquid outer core of the earth, partly composed of molten iron convecting through it. The theory explains the magnetic field associated with not only the earth but also the sun, stars and galaxies. The Earth’s magnetic field is similar to ... WebAug 26, 2007 · 16. The Magnetosphere. 17. Magnetic Planets. Until the middle of the 20th century the Earth's magnetism seemed to be a happy accident of nature. Too many factors had to fit just right--the fluid core of the Earth, its electrical condctivity and its motions, all had to satisfy the strict requirements of dynamo theory.
