WebMar 21, 2024 · As the BBC’s Jonathan Amos reports, a new map does just that. It was generated using data from the European Space Agency's Swarm mission, which is dedicated to studying Earth’s magnetic field ... Web90. A rectangular copper loop of mass 100 g and resistance 2.0Ω is in a region of uniform magnetic field of strength 3.0 T that is perpendicular to the area enclosed by the ring and horizontal to Earth's surface (see below). The width of the loop is a = 25 cm.The loop is let go from rest when it is at the edge of the nonzero magnetic field region. The magnitude of Earth's magnetic field at its surface ranges from 25 to 65 μT (0.25 to 0.65 G). As an approximation, it is represented by a field of a magnetic dipole currently tilted at an angle of about 11° with respect to Earth's rotational axis, as if there were an enormous bar magnet placed at that angle through … See more 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 See more At any location, the Earth's magnetic field can be represented by a three-dimensional vector. A typical procedure for measuring its direction is to use a compass to … See more Short-term variations The geomagnetic field changes on time scales from milliseconds to millions of years. Shorter time scales mostly arise from currents in the … See more Detection The Earth's magnetic field strength was measured by Carl Friedrich Gauss in 1832 and has been repeatedly measured since then, showing 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 … See more Earth's magnetic field, predominantly dipolar at its surface, is distorted further out by the solar wind.
