What happens to the diameter when the poles are more than 2?

Your request appears to be related to a specific context or topic, which isn’t fully clear from the information provided. When discussing “poles” in a general sense, the context can significantly alter the meaning: in mathematics (such as complex analysis), physics (like magnetic or electrical poles), geography (such as the Earth’s North and South Poles), etc. Each of these contexts could profoundly change the answer.

If your question refers to a mathematical context, for instance, involving poles in complex analysis or functions, the concept of “diameter” might relate to the domain or geometric interpretations of these functions, rather than a physical diameter which changes with physical poles.

However, without a clear context relating to what “diameter” and “poles” you are referring to, providing a meaningful answer is challenging. In mathematics, for instance, an increase in the number of poles in a function doesn’t typically correspond to changes in a “diameter” in a direct way, since those terms belong to different kinds of discussions.

For a more accurate and relevant answer, could you please provide more context or specify the domain (e.g., physics, mathematics) your question pertains to?
