Miniature magnets is a exhibit which illustrates the high strength of modern magnetic materials which are prepared from rare-earth metal compounds that are themselves extracted from solution by ion-exchange chromatography.

This exhibit is built on a metal-framed wooden stand with a large wooden model of a horseshoe magnet mounted on the stand.

Samples of the four magnetic materials Alnico (general composition: Al-Ni-Co), Boron Iron Neodymium (general composition Nd₂Fe₁₄B), Ferrite (general composition BaFe₂O₃ or SrFe₂O₃), Samarium Cobalt (two compositions are known: Sm₁Co₅ and Sm₂Co₁₇) are mounted on the large wooden magnet so that they can be reached by all visitors.

The magnet samples are held in place by aluminium rings and also protected by transparent plastic where necessary. At the bottom of the exhibit there is a tray holding samples of various metals with handles so that they can easily be manipulated. The samples of metals are (1) Brass Steel, (2) Stainless Steel and (3) Aluminium.
