Points of a magnet from which magnetic lines of force leave (north pole) and arrive (south pole).
Two meanings: (1) the points on Earth towards which the compass needle points. (Several slightly different definitions exist, because the field is not exactly that of a dipole.) (2) A concentrated source of magnetic force, e.g. a bar magnet has two magnetic poles near its end.
Those sections of a magnet (called the north pole and south pole) where the flux lines are concentrated and toward which they converge.
Either of the two points on the earth's surface where the magnetic meridians converge. They are not aligned with the geographical poles, but shift and do not lie exactly opposite of the other.
