WebMay 19, 2024 · There are three basic theories for how magnetoreception works, and they might all be accurate, depending on the animal. The first involves magnetic minerals. … Earth's magnetic field is generated by what is known as the geodynamo process. According to National Geographic(opens in new tab), for a planet to generate its own magnetic field by the geodynamo process, it must have the following characteristics: 1. The planet rotates fast enough 2. Its interior must have a fluid … See more Our protective magnetic "bubble," known as the magnetosphere, protects us from harmful space weathersuch as solar wind.

How does the earth

WebIn a sense, yes. The Earth is composed of layers having different chemical compositions and different physical properties. The crust of the Earth has some permanent magnetization, and the Earth’s core generates its own magnetic field, sustaining the main part of the field we measure at the surface. The Earth's magnetic field is believed to be generated by electric currents in the conductive iron alloys of its core, created by convection currents due to heat escaping from the core. The Earth and most of the planets in the Solar System, as well as the Sun and other stars, all generate magnetic fields through the motion of electrically cond… bioforlife
