They can eject billions of tons of coronal material and carry an embedded magnetic field (frozen in flux) that is stronger than the background solar … Generated by powerful, dynamic forces at the center of our world, our magnetosphere shields us from erosion of our atmosphere by the solar wind (charged particles our Sun continually spews at us), erosion and particle radiation from coronal mass ejections (massive … The magnetic field at … But about 41,000 years ago, the magnetosphere's strength plummeted "to nearly 4 percent of modern values" and tilted on its side, Mukhopadhyay said. Solar Wind Variations. Though Mercury's magnetic field at the surface has just 1% the strength of Earth's, it interacts with the magnetic field of the solar wind to sometimes create intense magnetic tornadoes that funnel the fast, hot solar wind plasma down to the surface of the planet. Outer core. The strength of Earth's magnetic field decreased by about 90 percent when a field reversal occurred in ancient past, according to Andrew Roberts, a professor at the Australian National University. The strength of the magnetic field is visualized by the closeness of the lines to each other. Electric and magnetic fields are produced by a fundamental property of matter, electric charge. The Moon varies in orbit around Earth, going from … The outer core of the Earth is a liquid layer about 2,260 kilometers thick. Coronal Mass Ejections (CMEs) are large expulsions of plasma and magnetic field from the Sun’s corona. Unlike Mercury, Venus, and Mars, Earth is surrounded by an immense magnetic field called the magnetosphere. Although it is always directed away from the Sun, it changes speed and carries with it magnetic clouds, interacting regions where high speed wind catches up with slow speed wind, and composition variations.The solar wind speed is high (800 km/s) over coronal holes and low (300 km/s) over streamers. Solar flares are large eruptions of electromagnetic radiation from the Sun lasting from minutes to hours. Though Mercury's magnetic field at the surface has just 1% the strength of Earth's, it interacts with the magnetic field of the solar wind to sometimes create intense magnetic tornadoes that funnel the fast, hot solar wind plasma down to the surface of the planet. Earth has three main layers: the crust, the mantle, and the core. In addition to sources in the Earth's core the magnetic field observable at the Earth's surface has sources in the crust and in the ionosphere and magnetosphere. All of this results in our Moon possessing gravity that is about 16.54% the strength of Earth's (aka. Saturn has an intrinsic magnetic field that has a simple, symmetric shape – a magnetic dipole.
