Magnetic field, a vector field in the neighborhood 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 lin
field intensity,field strength- the vector sum of all the forces exerted by an electrical or magnetic field (on a unit mass or unit charge or unit magnetic pole) at a given point in the field Based on WordNet 3.0, Farlex clipart collection. © 2003-2012 Princeton University, Farlex Inc...
These extra magnetic fields are generated by a set of three gradient coils that are placed within the magnet bore. As a consequence of these gradients, the same nuclei at different positions along the gradient direction will experience a slightly different total magnetic field, and therefore ...
