Iron Filings in Silicon Oil Model

Observation of three-dimensional magnetic field lines are stunningly brought to life in slow motion in this quality model as they slowly form around the alnico magnet in the center of the Silicon oil sealed chamber. The magnetic lines of force appear clean and well defined. This is the finest 3D magnetic field model we have ever seen! Dimensions 65 x 65 x 105 mm, approx. 360g, Alnico magnet (9 x 35 mm) 1 piece.
