Magnetic flux density calculation for high permeability material

AI Thread Summary
The discussion focuses on calculating magnetic flux density in high permeability materials, particularly in the context of a system involving two magnetically coupled solenoids with ferrite to enhance coupling. The Biot-Savart Law, which is based on air experiments, is deemed insufficient for these materials due to their different field distribution characteristics. Participants suggest looking into Maxwell's equations for a more comprehensive understanding of the relationship between electricity and magnetism. The conversation emphasizes the importance of understanding the magnetic flux that passes through both air gaps and ferrite in the system. Overall, the thread seeks guidance on interpreting FEM calculations related to magnetic flux density in high permeability contexts.

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!
 

Thread '3-terminal device external modeling'

Very basic question. Consider a 3-terminal device with terminals say A,B,C. Kirchhoff Current Law (KCL) and Kirchhoff Voltage Law (KVL) establish two relationships between the 3 currents entering the terminals and the 3 terminal's voltage pairs respectively. So we have 2 equations in 6 unknowns. To proceed further we need two more (independent) equations in order to solve the circuit the 3-terminal device is connected to (basically one treats such a device as an unbalanced two-port...

Thread 'Question about the voltage between two charged capacitors'

suppose you have two capacitors with a 0.1 Farad value and 12 VDC rating. label these as A and B. label the terminals of each as 1 and 2. you also have a voltmeter with a 40 volt linear range for DC. you also have a 9 volt DC power supply fed by mains. you charge each capacitor to 9 volts with terminal 1 being - (negative) and terminal 2 being + (positive). you connect the voltmeter to terminal A2 and to terminal B1. does it read any voltage? can - of one capacitor discharge + of the...

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...
