Finding forces/torques on a permanent magnet from a coil

AI Thread Summary
Calculating the forces exerted by a current-carrying coil on a permanent magnet, particularly for applications like electric motors, involves understanding the geometry of both the coil and the magnet. Key factors include the type of magnet, such as neodymium, and the specific design of the wire coil. Resources on computational electromagnetics are essential for accurate modeling and simulation of these interactions. While initial searches for academic papers may yield limited results, exploring specialized databases and research on electromagnetic forces can provide valuable insights. Utilizing CAD models can further enhance the precision of these calculations.

I want to know what methods there are for calculating forces by a current-carrying coil on a permanent magnet (the application I have in mind is electrical motors). I.e. given a geometry (like a CAD model of the magnet), the magnet type (e.g neodymium), and wire coil geometry, how are the forces calculated?

I tried looking for some papers but had no luck. I'll appreciate any pointers. Thanks!

I was using the Smith chart to determine the input impedance of a transmission line that has a reflection from the load. One can do this if one knows the characteristic impedance Zo, the degree of mismatch of the load ZL and the length of the transmission line in wavelengths. However, my question is: Consider the input impedance of a wave which appears back at the source after reflection from the load and has traveled for some fraction of a wavelength. The impedance of this wave as it...
