You can use Blender's geometry nodes to solve physics and electromagnetic equations such as Biot-Savart law. You can calculate the magnetic field of a coil anywhere in 3D space and visualise the magnetic fields. Additionally, you can see in real-time how the magnetic field lines change as the coil... gets deformed and twisted! #geometrynodes #b3d #blender3d #electronics #Engineering #Science #physics #kicad #circuitsshow more

Another demo this time with a spiral coil. You can see how the magnetic field lines change as I add more turns and change the height. Also added a point probe to display the field value!

really impressive! would be great as an interactive demo! all this offers great ways for much more understanding in electrodynamics. which is really a mystery to many students (and engineers)

Thanks! I will be releasing this soon, just needs a few polishing touches...

Oh very cool. Does it contain the magnetic field strength?

Yes, it calculates the field strength first and then creates the field lines. This is assuming DC current, I'm now adding the capability to calculate the inductance

🤯 Wow that's 🤩!! — Biot Savart is a nontrivial integration over (distance weighted) current vecors along the whole wire for every point in space. Maybe here only applied to the fieldline points in space to save compute. I wonder about the normal ⊥ equi fieldstrength surfaces.

I made it such that you can either choose between calculating over the entire volume or only along the field lines

Adding an interactive cursor showing local field vector and numerical field strength (B & H) wold be cool. — Further expectable forces when interacting with other coils or magnets. But that's a whole nother level up in difficulty adding a second integration.

great suggestions, thanks
