Magnetic Flux Density at different points about a solenoid
1. The problem statement, all variables and given/known data
For my physics investigation I am required to first find the theoretical magnetic flux denisty at different points about a solenoid. The points are outside the solenoid: along the axis but past the ends and; perpendicular to the centre of the solenoid but outside.
So far I have looked at many links to Biot-Savart law, but they only seem to show equations for a loop and not a solenoid.
2. Relevant equations
I have tried for the point along the axis:
but it only works with in the confines of the solenoid.
I also tried:
but it doesn't work for the solenoid.
What I basically need is two equations, one for the axis, and, one for the points perpendicular to the centre.

i was looking for this same equation a few months ago, bloody hard thing to find but i found it!
for a thin shell solenoid use the equation found here: http://www.netdenizen.com/emagnettes.../?thinsolenoid
for a solenoid with a shell use the equation found here: http://www.netdenizen.com/emagnettes...oids/?solenoid
