    Magnetic flux density calculation for high permeability material

    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...

    Getting Started with Maxwell 3D (ANSOFT)

    Hey jerrard, as i work on a similar problem, i can tell you for the case of a fully compensated system for coil number two, the induced electric voltage is U= M* dI(1)/dt. Therefore the phase in the difference in current phase is 90 degree, because you simply derive the sinusoidal current in the...

    Getting Started with Maxwell 3D (ANSOFT)

    regarding exporting field data for further use in matlab, i would like to ask for your help. To compare accuracy of two same geometrical models, but different settings for the mesh and error%, i need to generate a data sheet of all the scalar quantities of my B field (probalby a lot of data) and...

    Radio waves emitted by an inductively coupled power transfer system

    is that right? I really appreciate your help. I hope i am not making things more complicated as necessary here.

    Radio waves emitted by an inductively coupled power transfer system

    i fully agree that there is a rest of radiated power left in any real case. The main question, that probably narrows down my thoughts is, where the origin of the radiated waves that enter the vicinity arount my coils is. As there are two cases closer considered regarding my magnetic (and so my...

    Radio waves emitted by an inductively coupled power transfer system

    i guess that you mean coupling coefficient k= M/sqr(L1*L2)=1 by having a perfect flux linkage, right? That means, that the energy of the mutual coupled electromagnetic fields stay in the system with the two coils, the primary and secondary one. With respect to the perfect flux linkage, i now...

    Radio waves emitted by an inductively coupled power transfer system

    Unfortunately, i use Ansys Maxwell to simulate the coils and won't be able to detect any fields in a real case. Since the magnetic energy from the field, that does not influences the receiver coil is not transferred or used, it must go somewhere, when my electric Energy continues feeding by an...

    Radio waves emitted by an inductively coupled power transfer system

    I would like to know if a a inductively coupled power transfer system also emits electromagnetiv waves. The system contains of two inductance coils one generating the magnetic field with AC, the other picking up the magnetic energy and transforms it into an AC, also. The current frequency is...

    Getting Started with Maxwell 3D (ANSOFT)

    I want to see how my B field changes with changing Ampere with respect to the coordinate. Therefore i use an rectangular plot along a non-model line to see the change of my B field. Is there a way to calculate my B field with respect to my coordinate and several Ampere values? Since i don't have...
