Earth magnetic field lines
WebFeb 7, 2024 · The lines of force in this magnetic field are run from south to north. It is found that if a bar magnet is freely suspended, it will align itself parallel to the lines of magnetic force of earth. They are parallel lines near to the equator. The horizontal projections of these lines can be termed as magnetic meridian. WebMagnetic compasses have been used for navigation (using the Earth's magnetic field) since the 11ᵗʰ century. Interestingly, measuring the strength is considerably more difficult. …

Earth's magnetic field, also known as the geomagnetic field, is the magnetic field that extends from Earth's interior out into space, where it interacts with the solar wind, a stream of charged particles emanating from the Sun. The magnetic field is generated by electric currents due to the motion of convection currents of a … See more Earth's magnetic field deflects most of the solar wind, whose charged particles would otherwise strip away the ozone layer that protects the Earth from harmful ultraviolet radiation. One stripping mechanism is for gas to be caught in … See more Earth's magnetic field, predominantly dipolar at its surface, is distorted further out by the solar wind.
