Magnetic flux generated by a motor coil

AI Thread Summary
To calculate the magnetic flux generated by a motor coil, one must understand key equations such as B=(mu)NI/H for the magnetic field and flux=BAcos(x) for magnetic flux. The discussion emphasizes the importance of considering the presence of an iron core, which affects the calculations. Additionally, the Bio-Savart law can be used to visualize the magnetic field surrounding the coils and analyze the interactions between them. Resources like Wikipedia's solenoid page are suggested for further learning. Understanding these principles is crucial for accurate calculations and representations of magnetic fields in motor coils.

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.
 
Physics news on Phys.org
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?

Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'

So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...
