I am at a loss for the answer to something i feel I should already know. I am a machinist and regularly use switchable magnetic bases to solidly hold indicators in place. I am certain that someone knows exactly what I am speaking of. here are a few questions if you please:
1. What is the composition of the material which rotates within the assembly?
2. How do the constituent parts of the magnet operate to create a magnetic field that can be turned on and off?
3. (ahem-this is the crux of why I am writing), Once disassembled why is magnetism in all parts totally lost?
4. I know that the assembly can be re-magnetized. Is this easily acomplished? (With a mag-paricle inspection yoke maybe, or is there something that can be recomended to experiment with to do this on a small scale?) Where can I turn for a reference on this subject? --Thanks
