Magnetic Field 3D Chamber Model

The best Magnetic field model available. Unlike models that use compass needles to indicate the lines of force, the contained fine iron filings in this model demonstrate a true 3D shape of the field around a cylindrical magnet. Comes complete with magnet and a Perspex rod to retrieve the magnet.

Made of Perspex.

Approximate dimensions 110 x 115 x 115mm (LxHxW).
