how long does thing last

@lightspeedkiller

A couple of minutes, I beleive. It depends on friction between metal spheres.

for 1 00 peice it is 12 £ in england but for 1000 peice set it is 40-60 pound and btw it is called geo mag in england :P

Geomag (geomagsacom) and Supermag (supermagcom) are different magnetic constructors made by two different companies.

Supermag basically has magnetic rods of two lengths (1 and sqrt(2)) and non-magnetic spheres. Rods made of full-length neodymium magnet and plastic jacket thin on the ends so you may connect more rods on a single sphere.

Geomag has basically one size magnetic rods and panels to make shapes stable (since you cannot make stable square without diagonal rod).

Geomag rods are made of two tablet neodimium magnets and steel rod between them inside plastic jacket. The ends of the rods are rather thick so you may connect less rods on a single sphere.

I built an exact replica, but it wont go back and worth.

It's necessary to connect same-pole sides of rods on two opposite pushing spheres.

It is a bit hard to do since rods tend to connect plus-to-minus to reduce overall magnetic energy so the sphere remains almost magnetically neutral and pendulum just falls on one of the spheres.

But if you connect rods to sphere by the same pole (they will resist) then the sphere becomes strong magnet and if other two spheres (pendulum's and opposite's) have the same pole it works as expected.

my girlfriend would like this xD

@YurNick and slight air friction and slight gravitational pull from things around it (extremely slight, not even recordable)

Good idea, the video is very cool.

The word boner comes to mind. =O

@ScarFace9797 They have Geomag here in the States, as well. I own some. Magnetix is a totally different brand that my brother owns. We can tell you that Geomags are MUCH stronger than Magnetix, but Magnetix has a larger variety of pieces.

@freeskate247 called magnetixs here

[Devicon]

Reminds me of the spring door stoppers
