Magnetic flux density calculation for high permeability material

Click For Summary
SUMMARY

The discussion focuses on calculating magnetic flux density in high permeability materials, specifically in the context of a system involving two magnetically coupled solenoids with ferrite to enhance coupling. Participants emphasize the limitations of the Biot-Savart Law in such scenarios and suggest using Maxwell's equations for a more comprehensive understanding. The conversation highlights the importance of finite element method (FEM) calculations in interpreting results, particularly when magnetic flux traverses both air gaps and ferrite materials.

Hi to all of you,

As the Biot-Savart-Law is based on experimentations in air, i like to know how to calculate the magnetic flux density in material with much greater permeability, where the circular like shape of the field distribution troughout the vicinity does not apply.
Does anyone has a hint where to find some further information or can answer the question directly?

The question relates to a a system of two magnetic coupled solenoid with a number of windings, where ferrite is used to improve the coupling and is based on a FEM-calculation.
Edit: The magnetic flux passes through both an air gap and the ferrite.

To interpret the solutions, i like to build up a better understanding for the results.

Thank you for any hints.

Maxwell's equations are the more general descriptions of the relationship between electricity and magnetism.

Thank you very much.
The information is very good to find a good spot on the science ground for digging!
