If a magnet has a third pole than the third pole is called?

If a magnet had a third pole, it would be referred to as a "monopole." In theoretical physics, magnetic monopoles are hypothetical particles that possess only a single magnetic pole, either a north or a south pole, unlike conventional magnets which have both. However, as of now, no magnetic monopoles have been observed in nature, and they remain a topic of speculation and research in particle physics.
