The magnetic field on the z axis of a solenoid (in Gaussian units) is:

B=[2\pi(N/L)I/c][sin A_2-sin A_1]' date=' where A_i is the angle between a line perpendicular to the axis of the solenoid at one end and a point on the z axis. If you write this in terms of z and expand, you can use Legendre polyomials to find the field off the axis and the dipole moment of the solenoid.[/quote']

 

I thought this was a complete answer.

I do not know much about Legendre Poynomials. Can you expand the equation a bit in plain english?
