# Urgent Help Needed

I have been trying to derive a general formula for finding out the magnetic field at an axial point of a polygon of $$n$$ sides. Can you provide me with the derivation as I am in an urgent need of this formula?

Help would be really appreciated.

Thanks

It is easy. Just take the components of the magnetic field by each side and add them. I shall not provide the entire derivation as I've got mains tomorrow.
