Magnetic flux density calculation for high permeability material

In summary, the conversation discussed the calculation of magnetic flux density in material with high permeability, specifically in a system of two magnetically coupled solenoids with ferrite. The question also related to understanding the results of a FEM-calculation and the use of Maxwell's equations in this context. The conversation ended with gratitude for the helpful information.

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.

Related to Magnetic flux density calculation for high permeability material

1. What is magnetic flux density?

Magnetic flux density, also known as magnetic induction or B field, is a measure of the strength of a magnetic field. It is the amount of magnetic flux passing through a unit area perpendicular to the direction of the magnetic field.

2. How is magnetic flux density calculated?

Magnetic flux density can be calculated by dividing the magnetic flux (measured in webers) by the cross-sectional area (measured in square meters) perpendicular to the direction of the magnetic field. This is known as the magnetic flux density formula: B = Φ/A.

3. What is high permeability material?

High permeability material is a substance that allows a large amount of magnetic flux to pass through it. This is due to its high magnetic permeability, which is a measure of how easily a material can be magnetized in the presence of a magnetic field.

4. How does high permeability material affect magnetic flux density?

High permeability material can significantly increase the magnetic flux density within its vicinity. This is because the material provides an easier path for the magnetic field lines to pass through, resulting in a higher concentration of magnetic flux. This effect is commonly seen in electromagnets, where a core made of high permeability material is used to boost the strength of the magnetic field.

5. What are some common applications of magnetic flux density calculation for high permeability material?

Magnetic flux density calculation for high permeability material is important in various industries, such as electrical engineering, material science, and manufacturing. It is used to design and optimize devices that utilize magnetic fields, such as transformers, motors, and generators. It is also essential in the development of new materials with high magnetic permeability for more efficient and compact devices.
