Help me:Magnetic flux density(B) calculation

[surendhar]

Dear all,
I have a measured data of magnetic flux density(Bz) along the axis of the solenoid. I want to calculate (Br, Bz) around the axis of the solenoid. Please help how to calculate magnetic flux density component(Br, Bz) around the axis using the measured data(Bz). Thanks in advance.

I don't want to be stingy, but this is probably a question fit for the homework help section.
