I'm attempting to get a rough estimate on how the shape of an electromagnet pole will affect the field produced. Most of the poles you see in labs are tapered, and not simply cylindrical - I'm wondering how this affects the field. After all, there has to be a reason why they would do such a thing.
physically, I imagine that a very very narrow pole would have field lines concentrated strongly at the tip, giving a high B density but at the expense of uniformity. On the other side of the coin, a large flat cylinder will have field lines which are less dense, but more uniform.
My understanding falters in the middle, with a "conical" shaped pole.
If anyone can provide some insight i would be appreciative
