The missing word to complete the sentence is "poles".
Explanation
This question is about basic concepts of magnetism. A bar magnet is an elongated magnet where the magnetic field is mostly focused on the extreme ends. The ends of a bar magnet, where magnetic force is concentrated, are known as the 'poles'. The degree of magnetization tends to decrease as one progresses from the ends to the centre of the magnet. There are two poles for every magnet, one north and one south. These poles can attract or repel each other depending on their orientation in line with the rule that like poles repel each other while unlike poles attract each other.
