Nemesis Damage Report

[Dafni]

I wonder what RC Monster Mike will say to this.

I can imagine a hair-fine crack from the factory.
You could also get such a smooth crack by heat shocks, I guess. (like in glas) But this is out of question here.
I blame it on a manufacturing fault.


FYI:
The material looks and feels like cast iron. It's an alloy which also consists of significant amounts of Neodymium. Which is a Rare-Earth-Metal, so called Lanthanide. Pure Nd would be sensitive to oxigen. (I'm a Lab-tech here at the University of Berne, Departement for Inorganic Chemistry, and I work in the field of Rare-Earth-Metals, so I know a bit about these metals)
The magnet also has some sort of coating. Maybe to stop it from corroding??

This magnet is dead indeed. No possible way of fixing. As it cracked it generated new pole-centers, and as I pulled it out of the can, one part flipped around. So now it's impossible to get them together again.
