Earth geomagnetic field
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. So we could say that the Earth is, therefore, a "magnet."

WebSpace weather refers to variations in the space environment between the Sun and Earth (and throughout the solar system). Some space weather events, called coronal mass ejections”, start as eruptions from the sun’s surface. These events are common, occurring on average two times a day during the most active period of the 11-year solar cycle.
