Magnetic flux generated by a motor coil

sebitab

Hi,
I am not so good with magnetic equations and I am needing some advice in how to start to calculate the magnetic flux generated by a motor coil.

Finally I want to be able to calculate the magnetic flux generated with and without the iron core of each coil in the motor.

I will appreciate all information, help and links to learn about the matter.

how about the magnetic field of a current carrying solenoid .
B=(mu)NI/H (Mu)=permeability constant N= number of turns
I= current H=height
http://en.wikipedia.org/wiki/Solenoid
flux=BAcos(x)
where A= cross sectional area.
Is this what your getting at .

Thanks for your answer. But if I want to draw the magnetic field surrounding the coils and the collaboration between them canceling or summing force, It is correct if I do this with Bio Savart law?
