Designing an electromagnet simulation to calculate the magnetic flux density.
I am currently in the process of designing an electromagnet to harvest energy from overhead railway lines using Ansys Maxwell 3D. I need to get the magnetic flux density in order to then work out the voltage and finally the power of the electromagnet so that I can optimise the design. I am struggling to design the coil for the model and so believe any current results I am getting for the flux density is incorrect. The electromagnet is situated around the wire and therefore the coil needs to also follow this. Any help would be appreciated.
