Introduction  top
When Alnico-Magnets appeared years ago, I bought two sets of 12 bar magnets enough to build two cubes.
The bar magnets were one of my grandchildren's favourite toy at each age. Now they are getting older and I asked some of them (8, 10, 13 years old) to build figures for my homepage. Conditions were, the figures must be symmetric and all 24 bar magnets must be used. They did it with much enthusiasm. I show their figures on this page as 3D pictures. so they are better to be recognized.

So you must look at the following picture pairs with the 3D view.

01 Boat


02


03 Tetrahedron with centre lines


04


05


06


07

08

09


10

13 Prism with centre lines

What a pity. One ball is missing. But two cubes have 16 balls.

Here is the hexagon star made of 24 bar magnets.


My Adition    top
Cuboctahedron
...... If you fold the triangles downwards and form right-angled triangles with the outer bar magnets, a famous Archimedean solid arise, the cuboctahedron.
This is the pair.


Now you have the question, whether there are more figures with 24 edges known by names. I found five ones. 

Gyroelongated square bipyramid (Johnson 17)

Triangular orthobicupola (Johnson 27)

Truncated tetrahedron with three face diagonals

Octagon prism

Hexagonal antiprism

Four 3D figures
