How did earth's magnetic field form
Web9 de dez. de 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. Web12 de jul. de 2024 · Earth's magnetic field creates a 'bubble' around Earth that helps protect our planet from some of the more harmful effects of energetic particles streaming out from the sun in the solar wind. Some of the earliest hints of this interaction go back to the 1850s with the work of Richard Carrington, and in the early 1900s with the work of …
