PolymagnetJason

We knew it wouldn't take long for this question to come up...we would answer, but you would say we were lyin'...

Here is a great description from a great scientist...

First question!!

So if you look at the force curve for 1000425, the magnet shown in the pull test in the video, what you will find is another property of correlated magnets that is not highlighted in the video: we create force curves that have higher strength up close, and are weaker at further distances. We do this for both attraction and repulsion on the same magnet pair, balancing the two and using this advantage, to create a ‘zero force’ point that is above the surface of the magnet. We do rely on axial constraint in order to keep the magnets aligned by one degree of freedom, otherwise the magnets would simply fall apart to the side or flip over in the air until they stuck!

This is something that we have looked at, and this is a potential application for our technology.

We typically use neodymium magnets which have a very long life (greater than 100 years). Polymagnets have the same life characteristics as conventional neodymium magnets.

The life of a magnet can be shortened if the magnet is exposed to excessive heat.

Great thought. Our springs can be described mathematically like a mechanical spring...there will be a force depending on the distance from equilibrium. Not sure what it would take to make a magnet spring to avoid the valve float issue in an F1 engine, but it would be great fun to work on...
