Hi,
I am working on a COMSOL model trying to excite a coil with 25V and 1A using the lumped port method and a frequency excitation of 90kHz to be used for wireless power transfer for battery charging.
I have attached the file but the results do not seem correct, I feel as if the coil itself may not be defined properly and no current seems to be running through it. What is the best way to make the lumped port to work in order to excite the coil at a frequency of 90kHz? I have also attached 2 screenshots from a video seen online for the results I am hoping to achieve.
I also wish to attach the coil to a ferrite plate in order to increase the magnetic field strength, are there any previous examples on forming some kind of union or assembly between multiple objects to see how the magnetic field induced in the coil interacts with a ferrite plate underneath it?
Many Thanks,
Arnas
