Thingiverse-- Free 3D models, primarily intended for 3D printing. Magnetic simulation usually is the same as a low frequency electromagnetic simulation based on magnetic field only, without the electric part of electromagnetic field taken into account. It is electromagnetic wave visualization tool that I developed in MATLAB.
