So, for reference, the design of a similar strength electromagnet is described in this article. Many people will be familiar with fridge magnets, which typically have a magnetic field density of 5 mili Teslas. Providing the radius of the electromagnet core is no more than a tenth of the core length, the equations will be reasonably accurate (this caveat applies to most formulae for electromagnets). Magnetic theory can get a bit convoluted and before you know where you are, you can end up knee-deep in variables, constants, differentials, and integrals.This article reduces the theory down to a simple formula which, hopefully, will give you a feel for electromagnets and allow you to easily design a simple direct current (DC) rod electromagnet with a defined field strength at its pole faces.
