- On the surface of the planet earth, the point within the northern hemisphere where all meridians meet. It is defined as 90° N, and is the northern end of the axis of rotation of the planet. Also called north geographic pole, or geographic north pole.
- In a magnet or magnetic body, one of the two regions where the magnetic lines of force converge, and hence magnetic intensity is at a maximum. The other region is the south pole (3). Such a pole, when part of a magnet which is freely suspended, will seek a south pole, as opposite poles attract. Also called positive pole (1).
