3D view of magnetic field lines

Model for demonstration of the magnetic field around a magnet.

The model is from plexiglass, with a hole in the centre, filled with special ferrofluids (magnetic liquid). After inserting the magnet evenly distributed magnetic nanoparticles inside the fluid is arranged by magnetic field lines.

Material: acrylic, ferrofluids, permanent magnet rod

Dimensions (cm): 50 x 50 x 40
