How is a magnetic field measured
Web13 apr. 2024 · Coronal magnetic fields are at the heart of most of the unsolved problems in solar physics and of the solar–terrestrial relationship. However, no routine measurements have been carried out for the magnetic field measurement in the solar corona, due to the weakness of its signature. Web1 apr. 2024 · magnetic field, a vector field in the neighbourhood of a magnet, electric current, or changing electric field, in which magnetic forces are observable. Magnetic fields such as that of Earth cause magnetic compass needles and other permanent magnets to line up in the direction of the field.
